Thanks so much for your video !! Heard the fan blades making a rubbing sound. Sure enough i had ice buildup on the inside coils at top 3 inches. Took the water hose and sprayed the ice away. Got a call in to our ac company. Its a Sunday morning, so i hope they have the parts !!! Temp. outside is 40 with snow on the way ....
Thanks man it will help me a lot, avoid now this noise sound . step 1 turn off power step 2 use warm water step 3 dry everything with air or clutter . step4 turn on and enjoy the silence :).
When my unit was iced up almost this bad I switched the unit to ac and let that run for 20 mins it pulled heat from inside the house and defrosted the unit. I then did a continuity check on the defrost temp sensor and found it was bad. I replaced it. No more problems for this year.
I have a cheap DIY minisplit i put in a few years ago. What i do is put a cardboard box over the heat pump with a small square opening that fits a space heater in front. I am in a remote northeastern mountain wilderness with extreme weather. What i like about the space heater method, is that i can just run outside, set it up in, plug it in and come back in within 5 mins. The cons are it can take a few hours to really melt al lthe ice, but, its time i'm inside warm. I typically do this this a handful of times each winter in 5-15F temperature. I use the minsplit as primary heat source above 40F, and secondary heat source for under 40F to a wood stove. It earns its keep here and does a great job, even with this occasional annoyance. I also put a baby monitor in place to hear if the blades start hitting ice before the fan siezes to the ice after a defrost cycle.
@@AnthonyHoekstra Not true at all Anthony, you must live somewhere fairly warm. In climates where it doesn't get above 20F for a months straight and usually weeks never above 10F I guarantee your heat pump will build ice and work poorly. ALL heat pumps I've seen do this. Dennis has one of the only practical solutions to this: Either don't use it during the coldest part of the year or manually defrost it with an external heat source. And, no, even fully defrosted it is not 100% efficient at -12F. Those datasheet specs are not true if you actually test them yourself.
I did yesterday the procedure to one old Toshiba air heat pump. It’s installed to one old house and primary mission is just keep the inside over +8 degrees of Celsius. At winter that house is empty. The problem in this kind of use the heat pump can’t generate enough defrost energy from inside and it starts collecting ice. But if target temperature is set to 21 degrees of Celsius there will be no problem at all. Greetings from Finland.
I would do this only if its above freezing because if its below 32F it will just freeze all over again in a matter of time. On coils and copper pipes, never use boiling hot water because it will cause a burst in the lines from a very quick temp change from cold to hot.
You have to defrost it to fix it. You can defrost a Heat Pump this way below freezing. Tap water is 55 Degrees. It wont freeze over again like this one if you fix the defrost correctly
If you don't have a hose in the winter time get a 3 gallon hand pump sprayer. Fill it up with hot water in the tub then go out side and de-ice. Repeat as much as needed.
Have the same issue. Changed out defrost board and sensor. Still freezing up...air filter change new, new thermostat (two years old)..no vents closed..any suggestion..have a carrier 2014 unit package unit?

I dont understand why they have these units in the U.S? In Australia for ducted we have Thin tall vertical units with 2 fans, they ice up in winter but always defrost. And the compressor has a blanket around it.
we call those units mini splits. we use ducted systems because it is much more efficient to cool a whole house. not heads. we call those ductless mini splits but we use those for garages, workshops or any house additions and sometimes whole houses.
They are common in Washington state where the winters are mild, we get snow and sub 30F for perhaps a week then temps go back up to mid 30's and frozen heat pumps become a non issue. The 18F this winter was an anomaly.
oh my god lol this is wrong your not supposed to put water on somthing when its cold it will literally just freeze the entire unit will not have ice on it it will be a solid brick of ice
Really?? Unplug the fan wire, go to thermostat and turn on AC. Let the hot gas melt the ice. Who in their right mind would stand outside in winter with a garden hose, spraying the coil? Lol
Very helpful over here.Love the no commentary angle and I busted out laughing at the boil an egg bit hahaaa thanks for the info and the laugh.

step 1 turn off power

step 3 dry everything with air or clutter .

This only helps defrost the hp to work on it. Besure to fix it so it doesnt freeze up again or your HP will freeze up again in no time
How did you dry the unit before start up? Or did you just start it up wet.

When you do it this way. Remember to disconnect the outdoor fan

a good Daikin fit mini split is 100% efficent up to 112 degrees and down to -12 degrees

Excellent post Dennis. Honest commentary is getting harder to find these days

That's also my problem trying to melt my basement unit which is only set at 17.

Oh wow thanks for this comment because I just started boiling water 😂😂😂

How do you check if sensor and defrost board are bad besides the unit being iced over?
Call your local HVAC company and have a professional check those components...
You can do a continuity check.
Visual inspection of the Defrost board and/or test the sensor. If one is bad, besure to replace the other also
Is that even safe with the water ?
Have the same issue. Changed out defrost board and sensor. Still freezing up...air filter change new, new thermostat (two years old)..no vents closed..any suggestion..have a carrier 2014 unit package unit?
Low on refrigerant possibly

@@minoc6319 you just called it coolant and refrigerant at the same time, get a professional involved to look at it asap

Do you think the US is Located at the North Pole?

Our systems defrost too.. i don’t know why this guy is manually defrosting this unit. It needs a new defrost board

How do you turn off the power??
Service disconnect at the unit or just turn off the breaker at the panel.
Very helpful!
Excellent!
that is what you call force defrost,is not wired right,or board or t stat bad.tin tirin.
Your defrost control board is bad.
Ya Think?! lol
Or defrost thermostat or low on charge or bad run capacitor or bad outdoor fan motor
Or reversing valve not shifting
Isn’t that just going to freeze?
No, Tap water is approximately 55 degrees
Run it in reverse with lots of nichrome heat!
