Ok - thanks to this board I thought I had found my solution, but now I'm stuck.

Front frame was getting very hot - in fact the plastic turned brown and started to crack. Determined that the Condenser Fan wasn't running (coils were clean). Order new fan - installed - still doesn't work.

So, next in line was the power control board. Ordered that up, installed, condenser fan still doesn't run. Everything else in the fridge/freezer seems to work fine - no issues with cooling, etc. But it's just getting super hot and now I'm at a loss. In the meantime I have a little fan up there trying to keep it cool.

One post on another board suggested that sometimes the Inverter box has to be swapped out to get everything working again. Anyone have thoughts on that - or another next step?

If you replaced the control board W10219463 then the only one left is the inverter board. Check your schematic, condensing motor wires probably come from the inverter.

thanks for the reply. to be clear, i did not replace the master control board W10219463. I had read that the likely culprit might be the Power Control Board 2259350. And the master control board is no longer made and not available (so i'm hoping it's not that!!).

So, everything works except the Fan does not run. The compressor gets really hot, as do the copper tubes that run down into the frame.

If trial and error is the only path here, so be it. I'm just concerned that I'll replace the Inverter box and it still won't work. Then I'll get advice that the compressor must be bad so I'll replace that and the fan still won't run. And then someone will say it must be the main control board - but you're SOL since they don't make those anymore.

Is there a test I should be performing to narrow it down?

For the life of me I cannot find the power board on the wiring diagram.
So either I am still asleep or your unit is somewhat different.
Makes me suspicious of the tech sheet accuracy when it comes to your unit.

When I look at the power board, it looks like it is just a DC power supply.
Probably just supplies DC power for the control board etc. but am not sure.

The tech sheet does show the condenser fan as being 120 volts.
The tag on the motor should confirm this.

I would check the power across the condenser fan just to be sure that it is not getting any. It is not unheard of to get a part that is bad.

I do not think that the inverter board should effect the condenser fan but am not 100% sure.

If it was me I would jiggery pokery a fix.
Wire the fan directly into the 120 coming into the unit.
Be sure to also ground it, if it currently has a ground.
It will rum all the time.

A more elegant solution would be to get a normally open thermostat and then wire it into the fan circuit so it turns the fan on when it gets hot/warm up there. Just be sure nothing can short out.

thanks for the help. yes, i changed out the power board, which probably wasn't necessary.

I think you've summarized exactly what i plan to do...get a fan and just let it run up there all the time. I have some experience with thermo-controlled fans as well (for a media cabinet that was getting hot), but in this case i think i'll just get one that can run all the time.

If that keeps things cool i should be okay for awhile.

I would use the fan you just bought. It mounts where it should for the proper air flow.
