Greetings all, sorry for the long post fellas, but I have a Frigidaire FRS26HF5AW2 SxS that I've been trying to troubleshoot throughout this Thanksgiving holiday, and have been storing our food in coolers in my truck outside. It wasn't cooling. No fan or air blowing inside.
Looked at the back and it was dirty, but the condenser fan was working so I vacuumed the condenser fins and everything underneath.
I unplugged the unit.
I took off the ice maker and the freezer panel. The evap was frozen over solid and the evap fan was unobstructed BUT not running.
It had a combination of "snow" encased by ice throughout.
I removed the wires going to the defrost heater and got a 34 ohms reading using a digital meter..
I should of left the defrost T stat encased in ice to check it but didn't. I used a heat gun to melt the ice instead and clipped the wires and removed the defrost T stat.
It showed a "1" on my digital meter at room temp.
With it being like 20-25 degrees today, I placed it outside on the porch for 1/2 hour, then stuck it in a bag of ice for good measure and checked again
but it showed the same reading of "1" hot or cold..
By now I was thinking this T stat is bad, but I did some additional tinkering.
I left off the stat, and twisted the wires it connects to together, bypassing it, plugged in and the compressor and evap fan came on and it seemed to run like it should.
It ran for about 1 hour then shut off. It went into defrost mode. I checked this by placing my hand near the evap/heater and it was warm and melting what little frost accumulated away. Now I was certain the stat was the problem...or so I thought..
For the heck of it I re-attached the defrost T stat, and once again, the evap fan didn't come on just like before so I removed it, again..I retested it, cussed at it, and had a stare down contest with the thing.
After doing hours of research, and running out of options, I decided to just put it back on and leave it alone, but not without plugging it in one more time..
Lo and behold everything kicked on. Compressor, both fans. etc. I let it run.
I noticed that it would periodically shut off and on, every hour or so. I I let it run overnight hoping for the best....
Next morning (Thanksgiving) it was running but no where near cold enough.
So the thing seems to be running ok and it tries to cool, except that it seems to be going into defrost mode at way too soon of intervals?
Is the defrost T stat bad, causing this by and producing the short defrost times?
OR could the ADC/board/timer be bad, or both?
I wish there was a way to bypass the defrost cycle or heating element, like I did the T stat, just to see if it will get cold enough, in order to eliminate a system seal problem?
I have to do something desperate since parts are hard to find, and even the defrost T stat is going to take 1 week to deliver....I can't afford to replace the unit with another used one at this time so I need to do what I can to nurse it along somehow or use my old Ford Explorer as our fridge ..Any help or tips would be greatly appreciated, thanks. -JC
