You've helped a poor college student renting an apartment with an old style General Electric thermostat. Thank you so much! I'm trying to be more efficient.
I found your videos when looking for a reason why my suburban RV heater. The problem I was having was the heater would not come on at all. No fan, flame, or attempt at ignition. I took the cover off of my thermostat and I adjusted the small dial and it worked. I don’t know why that made it come on but the unit is only two years old and I think I will have to replace the whole thermostat. Now I find myself watching more of your videos, thanks for all the info.
When I was cutting my teeth on furnaces I ran into some old camstat thermostats that were extremely picky, so I had to learn. There were also some Trane commercials that had such a low draw thru the electronics that we had to add a relay in parallel to draw enough for a mechanical to work. About the .8, hey if it works, who cares? Thanks GFM
Hi GFM, I've come back to your videos several times over the past few years. We have a new millivolt thermostat (Honeywell CT33) connected to a new propane gravity floor furnace. It works fine during the day, when we're moving around, but at night the furnace stops kicking on, and the place gets very cold (it's a little mountain cabin). Even during the day sometimes, the heat won't kick on, but as soon as I walk up to the thermostat, or sometimes touch it lightly, it will start. Our thermostat doesn't have an anticipator, I don't think, just a brass-looking screw near the top of the bimetal coil that looks to be some sort of connection adjustment. Anyway, have you encountered anything like this, and if so do you have any ideas? Thank you.
I have a Coleman deluxe blend air 2 . I just replaced the thermostat with a Honeywell home ct31A1003 . It came factory set to .4 but my question is. is that the correct setting for that furnace .And basically you can just play with this thing to adjust it to your home space & size. basically pinpointing how long you wanted to run before it turns off or turns on???? Finding that sweet spot of heat and when to turn off before too cold ? So instead of shutting of exactly on 73 degrees it gives a minute more before shutting off
Your goal is to have your furnace run for 5 to 10 minutes to maintain temperature in the structure. Of course, lower outdoor temps will mean longer cycles. You should not be able to feel a difference in structure temp as the furnace cycles. GFM
My apartment is getting too chilly before the heat kicks in. Where do I set the anticipator please. Do I want more cycles per or or less? Can you just spell it out for me. Thanks so much.
You want more cycles. Without the anticipator, there will be a lag where the temp must drop about 2F before the thermostat can sense the change. Then it will overshoot 2F before the thermostat senses the rise. The anticipator "anticipates" the drop in temp and turns the system on a little early. Then it shuts off a little early "anticipating" the rise in temp. Hope this helps. GFM
Great video! I have the same exact thermostat in my Winnebago 27' motorhome. It is a Suburban NT27SP. I called Suburban to ask them the setting for the anticipator. They said it is .78......where would I put my probes on my multimeter to check the amp draw for this thermostat? The furnace is wired for 120 volts @3.5 amps. David 🚀
I don't have a clamp meter, so I disconnected the wire coming into the W screw, put my red probe on it and put the black to the screw on the W and turned on the thermostat. It read 7.5 but the spec that is stamped on the front of the furnace says it's wired for 120 @ 3.5 amps. I don't understand. Thank you, David
Hi there I m having issues ..my home is too cold I did wait for 2 days but still the same...so can u help me on this n I dnt know which number in longer cycle makes hot n cold..so could u tell us that
What bout cooling, does it work the same ? --- anticipator... I'm having trouble keeping the air running after 7pm. It won't start up again till maybe 7am . It's a old rectangle Honeywell heat pump therm. Fan works all the time (brand new), is that right ?
The anticipator for cooling is of a fixed size, because it is energized in the off cycle of cooling. So I don't think this is your problem. If the fan is running all the time and the fan switch is set to auto, the unit could be freezing up and not thawing until the morning. Hope this helps. GFM
I just had a new fan motor put in, I turn the unit off & I can switch the auto on - it works, then off - goes off. Then turn unit back on & the fan motor comes back on. Could it be wired wrong ? It has gone off but only twice that I know of. It works all the time. I'm in Phx. Az. so stuff heats up pretty quick. THX
Ok I have another honey well ,vertical rectangle bottom slide temp adjuster, Sorta got the anticipatory figured out, I measured my am drama at .27 Amos. On my adjusted. Arm. There is a little thumbs catch and what seems like a small arrow on the outer tip next to the thun catch, and a blunter arrowish bump 180 deg. at the opposite inner end. Which is the correct end. Compared to those inner arrows on yours mine is not a detailed atrow. And what's a defined cycle, Burnet on to burned off. Or blower on To blower off Miller hot air Wayne burner Mobil home unit. Ok thanks
Question!!! What do you think it could be if my A/C just basically almost quits working? Its pushing cold air out but not making my house colder! A little late too call someone but was just wondering
I wonder if you can help me, our living room thermostat wasn't turning on at 20 degrees like it normally does this week, we had to turn the the thermostat to 23-24 for the heat to come on, so we had a new thermostat installed and we still have the same problem with the new thermostat, this morning it was registered 20 but it wasn't that at all, I had left it on 15 over night, would you know what the problem might be? In the instruction's it talks about anticipator setting but there wasn't a anticipator on the old Honeywell CT 43 A thermostat, it's the old style that you adjust yourself, we have baseboard heating! the new thermostat does have a anticipator, but very unsure how to adjust it, I have phoned White Rodgers and they said to leave it on 4 which was the default setting, many thanks for any help.
I am considering switching from the old Honeywell mechanical thermostat to a Honeywell programmable thermostat. My question is how can the cycle be adjusted? I have looked at the Users Manual and there is no anticipator adjustment.
My house is too hot during the day and night doesn't get cold goes up to 78 need help thank u I clean the ac coils already it's clean I feel the air being thrown but not cold
My heater won’t shut off when u use it right now from your video I’ve made the cycle shorter I don’t have this problem with the cooling aspect but I just began to use heat and it just stays on....
So my toddler climbed up and spun that dial thingy an unknown number of times an unknown direction! And now the heater doesn’t work…where would I start?
There is no answer that covers all applications. Just set it toward long cycles and check if the unit stays on so long that the temperature difference is noticeable. GFM
First, I would check for power to the unit. Try turning on the fan switch. If the fan does not come on, check the switch on the furnace and check the furnace breaker. GFM
If the furnace is overheating the structure, you can first try removing the R terminal at the thermostat. If that stops the problem, the thermostat is at fault. GFM
@@grayfurnaceman thanks so much for the quick response. I know my apartment complex is older, but through my research, my model number is 1c20-101, which is a similar look to the one in the video, but with the “white Rodgers” logo. But it’s definitely mechanical, as the maintenance guy said it gets power from an outdoor transformer
I went all the way around, my heater sounds like it wants to start but then it just shuts off. I've had a maintenance man come by and told me everything was fine. I don't know what else to do. Sometimes it'll work, just annoying at the moment. maintenance man said it might be the thermo. Anyone else have any suggestions?? Cold on Christmas Eve.
If the furnace was built within the last 30 years, It could be a dirty flame rod. You can tell if it is the thermostat if you set it 10 or so degrees above the temperature. If it works, it is not the thermostat. Hope this helps. Merry Christmas. GFM
@@jacksonmclaughlin195 There should be a system switch on the thermostat that can be set to off. Some very simple thermostats do not have one and other than turning them down, the only way to shut it off is either by a switch on or near the furnace or a breaker in the panel. Hope this helps. GFM

There was probably a bad connection in the anticipator dial. Replacement if probably best.

Thank you, the too hot, too cold is what was happening with our radiant floor heated apartment. This addressed it nicely, commencing experiment.

Millivolts systems are very sensitive to connections. I would want clean and tight wire connections.

it will work better if they would set them up properly though, but that's asking for to much around here.
Hi there I m having issues ..my home is too cold I did wait for 2 days but still the same...so can u help me on this n I dnt know which number in longer cycle makes hot n cold..so could u tell us that
The numbers are just for the cycling rate. Probably not your problem. Does your furnace sometimes fail to start?

Could you do a vid on adjusting the antisipator on the Honeywell
Round heat only CT87K
These have a disk battery also
And some printed cricket boards.
They are adjusted by the cycle dip switches on the subbase. Look up the install manual for that thermostat.

Question!!!
What do you think it could be if my A/C just basically almost quits working? Its pushing cold air out but not making my house colder! A little late too call someone but was just wondering
You could have low charge or a failing compressor. Just a couple of possibilities.

First, is the replacement thermostat a low voltage or high voltage one?
GFM
@@grayfurnaceman I am not sure, Switch Rating 24VAC heating 0.15 to 1.2Amps
Its low voltage. It probably energizes a contactor. The contactor may be sticking.

@@grayfurnaceman thanks for the tip.
Thank you for the help!!!
I am considering switching from the old Honeywell mechanical thermostat to a Honeywell programmable thermostat. My question is how can the cycle be adjusted? I have looked at the Users Manual and there is no anticipator adjustment.
Depending on the model, it will either have no adjustment and will go to 6 CPH or the cycles can be adjusted in the installer setup.

Replace the thermostat.

Mines hooked up in garage it's a gas heater what should it be set on to keep it going on long cycle
There is no answer that covers all applications. Just set it toward long cycles and check if the unit stays on so long that the temperature difference is noticeable.
GFM
My air will not kick in and it's so hot! What should the anticipator be on for cold air?
Anticipator setting cannot be changed for cooling. I would first check the fuses for the outdoor unit.
GFM
What if its only heating? Like either on the cold side or hot it's HOT! Help !!
Hello what number is for shorter cycles I have the problem that it gets to hot or to cold help please
The lower the number, the faster the cycles.
GFM
I have this thermostat and it won’t turn on my heat or air conditioner? Can u help before I spent $ on a consult pleeeaassseee
First, I would check for power to the unit. Try turning on the fan switch. If the fan does not come on, check the switch on the furnace and check the furnace breaker.
GFM
Ok so Um yeah that switch is on the actual unit outside?
Thank you so much I’ll try that
You mean that you don't set them to .8a automatically? lol, that seems to be the norm here but don't hate us because of that!
What if my heat won’t go off how do I fix that on this plz
If the furnace is overheating the structure, you can first try removing the R terminal at the thermostat. If that stops the problem, the thermostat is at fault.
