Hi,

This unit is not cooling. I took the back off and it has one of those plastic boxes sitting
right next to the compressor and the wires run to the compressor. No relay or overload.

To be honest, I'm not familiar with this design.

I probed with my volt stick all around the area and there's tons of power there.

But, no compressor running and no condenser fan running.

Any help is much appreciated, as usual.

Thanks in advance,
Bruce

Test your compressor, if it tests fine, then more than likely your problem is in that little box ie inverter compressor control http://www.repaircli...0133449/1381553

Thanks Fellas,

I changed the Inverter and the compressor fired right up and the unit is cooling down right now.

BUT, until I left the customer's house, the condenser fan never came on.

Does this unit have some kind of delay through the computer scheduling it when to come on??

Or does it sound like another problem?? Maybe why the inverter went bad in the first place??

I told the customer to keep his eye on the cooling and call me at the first sign of lessened cooling.

Thank you,
Bruce

OK. I had to go back to this refrigerator a couple of days later to fix a leaking water line.

The unit is nice and cold, but I noticed the condenser fan was still not running.

Also, no power to the fan motor.

I guess I need to change the relevant control board.

Which board is it and where is it located??

Thanks,
Bruce

Bruce, have you been able to obtain and read a service manual for this unit?

If not, that would be the first thing to do before condemning the main controller board.

I have no idea if the KitchenAid all electronic control refrig would have this feature or not but I have seen it in I believe the Samsung's, actually have an ambient air temp sensor and depending on the reading the condenser fan will have a delay start-up, the colder the ambient air the longer the compressor runs without the condenser fan turning on so that the compressor oil will get up to the correct operating temp. I believe in the ones I've seen this in if the ambient air temp is above 70 degrees the condenser fan comes on immediately with the compressor and then there are two different delays, (I believe a 5 min. and a 10 min. depending on how cold the ambient air is).

It does sound like you have a main control board issue if you've never seen the condenser fan run at anytime when you've been working on it. If the wiring diagram only shows the refrig and freezer thermistors/sensor and no others then it wouldn't have the above feature.

I believe the main controller that has the relays that power all fans and other things is the one down at the bottom under the refrig, (not the one in the control console).

Thank you Gentlemen,

I replaced the main control board as a follow up and the condenser came right on.

Learn something new everyday with this digital crap.
