You can say that again. I may have started the site, but I will be the first to tell you that I'm no expert on all brands.

I learn new things from my own site all the time.

Never thought I would have degenerative spine disease, but there you have it. Nothing personal.

Sorry to hear that.

Maybe it's time I quit hanging around here so much.

Don't even think about it buddy! I have learned a lot from your post.

I have always felt very lucky that you take the time to contribute so much to our site when you have a site of your own too, thanks!

btw: I also enjoy Repair-mans site a lot, as he can tell you I check it constantly through out the day to see if there is anything new. :)

Well, you bypassed the main board to force it to run, so the symptoms now are a sealed system issue on the FF side. Whether a leak or a restriction, this will have to be determined by a certified refrigeration tech.  All of this will cost about 1/3 the cost of replacing this unit.

BTW, SubZeros always have access valves or pinch-off tubes to do sealed-system diagnostics from. If the unit  is low on Freon or runs excessively, it will cut out. If you don't know what type of refrigerant it has, read the model  says what kind and how much.

Thank you for your feedbaack!!
It does not have any circuit board, I just bypassed the thermostats, they are both screwed up, do not open and close any where near the correct temps.  I see I can them for about $50 each, no big deal.  I further disected, it is a round device that opens and closes, clicking, I assume this is the thermal over load protector?  Question is, is it bad, or is the compressor drawing too much current?  I also see a relay, that if I understand correctly switches between the start windings and run windings, could that be bad, causing the compresor to run on the start windings?
It is R12, can I still get that recharged?
Thank You !!!

If it blew the thermostats, chance are the compressor is bad or has shorted windings. Regardless, you  may not find anyone with any R-12 in stock to do this for you, and converting the FF side to 134-a requires a new compressor, condenser and evaporator coil. I think I'd be shopping for a new fridge, since you could have a repeat episode on the other side later down the road.

You can use R-414b all so known as 'HOT SHOT' . But I find that R-414a works better than R414b. In fact if you do warranty work for Whirlpool's non 134a systems you are required to use R-414a. this is on Whirlpool household Refig. & Freezers. Plus you only use 80% as compared to R-12.
Check the Basics first!!! Read the Manual !!!Buy the tech a Beer!!!
