Great video OC, thanks for sharing, I like your idea of ohming out the heater coils before you put in a new clock, that can save a lot of frustration and time and money.
At the end where you check the # 3 lead for short to ground.. could you put an inline fuse in the #3 wire to protect the clock in the event of problem with the heater or it's circuit drawing more than say.. 20 or 30 amps?
You know , i think u probably could. Id size it at twice the Amp draw of the Heating Element amps. Nice idea. I think it Might save some stress onthe rime clock in the event of A Heating element shorting to ground. I ve never seen it done though. Try it , let me know.
Great video, I'm new to the trade 1 yr out in the field and the electrical is what I'm struggling, my boss uses the same method "hopscotch" but I don't quite get it, maybe is the way he explains it or I just don't get it, can u upload more electrical videos....thanks in advance 👍👍
I Remember way back when i started , electrical was very difficult to grasp the troubleshooting. It will just come with time. Maybe grab a few electrical troubleshoiting books at the library. If u get the opportunity to go to carrier training school - thats where i learned hopscotch. Very good training school. Take Tech 1 & Tech 2 Training classes. What state are u in ? California ?
Hopscotch is basically explained by Putting your black lead from your meter on one side of the circuit , lets say your troubleshooting a 24 volt circuit. Black from your meter would go on common side of transformer you leave it aligator clipped to the common on the transformer, Then You hopscotch through the circuit using a wiring diagram to find the open with your red meter lead starting at transformer 24 volt red side , testing each point on the wiring diagram to see where u loose 24 volts on Your meter. Its that simple.
I went to carrier school in city of industry. 1983 & 1984 So, its not that far away from you. Call carrier and see if they are still doing school in city of industry. See what it costs. I took Tech 1 & Tech 2. Classes. They teach schematic reading in depth & hands on troubleshooting in the class room & Workshop with equiptment. Very excellent school. You get Diploma too. And class picture.
Hi guys, My norlake walking freezer just stop working. Defrost timer panel looks like no power, the green light on panel is really weak flashing. Comp and fan not start at all. Can any one help?
Highly recommend u call a Refrigeration service company for repairs. If your not going to do that - Turn off the Power at Breaker panel & Look for burned wires in Freezer compressor panel & inside evaporator. If burned wiring found repair as necessary. If none found: turn power back on & Turn time clock. So Green light is on & Red light is off. Cooling mode. If u want to replace a Part - The defrost clock is a good place to start if it’s over 10 years old. common failure. Get Your voltmeter - if u don’t have a voltmeter Or know how to use one. Call a Service company. If u do - From N to 1 on time clock - you Should Read Line Voltage. Either 208 or 115 volt. Whatever the Power is that’s supplied to the unit. If no power - u have a incoming power issue. Call - a Refrigeration Service company. a Good visual inspection with the BREAKER Off !!!!! can find a lot of problems. Make sure power is OFF !!!!
Freezer evaporator Must be Below 30 degrees & Fan(s) MUST be Operating then put freezer in defrost, set defrost time at maximum over 1 hr , when evaporator coil temp hits 50 degrees+ power will be applied to x , and defrost clock will pop out of defrost & switch back into cooling mode. it at this point in time when u can measure voltage between x and N. You will read voltage at this time until evaporator temperature drops below 50 degrees and fans ARE ENERGISED / Running. at this point you will no longer read voltage at x if Everything is working as it should.
Also --- As a Side note. if Freezer Defrost time clock is over 10 Years old. Replace the Defrost clock as a Maintenance item Every 10 Years. Thier is a Date tag at the top of the defrost clock. Defrost clocks Fail ALL THE TIME. The clocks stop turning , they stick sometimes intermittently , Remove clock and check for burned points in brass contacts area , they dont keep correct time , if it does not turn smoothly , replace the clock.
thats a Grasslin time clock those go bad as other techs they go back with the old school mechanical time clock the Paragon 8145-20 a very reliable clock. as new stores with rack systems its all computer now but older racks will have these. as a new electronic time clock out there is the paragon 9145-00 it will replace the Grasslin runs on 120- 208-230 volt.
At the end where you check the # 3 lead for short to ground.. could you put an inline fuse in the #3 wire to protect the clock in the event of problem with the heater or it's circuit drawing more than say.. 20 or 30 amps?
Dude, you’re the man, thanks for being humble about your knowledge
Awesome video, man. I really appreciate you showing us your troubleshooting. It will definitely help me, thanks, mate!

Great video! Thanks for sharing. I learned some great tips. I have a similar heatcraft setup for our walk in freezer.

Nice to see you doing videos bro I bet it's pretty hot in orange county now I haven't been there in a while
Hasn't really been that bad yet. Im by the south coast. So i don't get the inland heat.
Where is your neurtal hooked up at? Where is your lead? The contactor?
Very good video, thanks for that great information
Your welcome.
Great video sir.
thank you ! Yea , it came out well.
great explaination video
Thank you ! Glad u liked it. Thanks for Watching & subscribing.

Take Tech 1 & Tech 2 Training classes. What state are u in ? California ?
in the winter time, when it slows down, ill be putting up alot of electrical & electrical troubleshooting videos.

Can you share carrier training class info please.

Universal voltage for a time clock?
Yes. Only for digital models. Analog clocks / intermatic are Not Auto select voltage yet. You still have to select voltage and model type for analogs.

How do you check × ? thanks

Use a contactor for it
Is that a Heatcraft?
The Condensing unit on the Roof is a 9 Year old Heatcraft. The Evaporator is 9 years old too but, i am not sure its a heatcraft or not.
At the end where you check the # 3 lead for short to ground.. could you put an inline fuse in the #3 wire to protect the clock in the event of problem with the heater or it's circuit drawing more than say.. 20 or 30 amps?
I suppose u could. Just never seenit done. But, makes sense.
