Osu!
Have the above ca 10year old unit. It stopped getting cold. Unplugged let defrost completely. Read a bunch of forums, and checked the usual suspects...My main board (the $180 one) had a blown out solder joint on the rear of the 832A-whatever relay (the one which looks like two rectangles stuck together next to the oblong blue thing).

Decided to reheat the solder joint to "reconnect" it to the board...all went briefly well! Replugged and it got cool in frige and cooler in freezer but not to spec...got to about 54°F in frig and ~35°F in freezer overnight. then the compressor did the short cycling thing where it would run briefly, go off then about a minute later, briefly run.

One thing I do wonder about is the conderser fan. It seems to run at about ~120 rpm or so and is easily stopped. It doesn't seem to have any torque at all...what is the typical rpm / strength of this fan?

Can this limit the cooling to a certain point where the compressor will then be overheating and then shut down? Please help and thanks!

PS-any other insight to check next would be appreciated...start relay and run capacitor may also be at fault? should i get a hard start kit if the fan is okay? thanks again!

Yes and yes!

These dinky condenser fan motors are famous for slowing down on the job. But check the voltage from the Muthaboard to the fan, details on this page:

If the fan's supply voltage is within spec, then replace the condenser fan motor:

Greetings all!
Thanks for help and advice...I replaced the condenser fan motor and the unit has been running for about a week now...domo!

PS-the new motor doesn't seem to be much faster than the old one but it may have more torque...at this point, I'll just let it run...!
