Ge refrigerator not cooling

[remunguia1]

Hello all, I have a hot point refrigerator model number hsm25gftasa and it is not cooling. Nothing on at all only lights when I open door. I looked at the back and found mother board. Anyone know where I should check voltage at? I checked 3 prong connector on bottom and gave me 120v. I need to know where to check refrigeration side. Service manual? Schematic? Please let me know thanks!

Flip that control board over and look for a burnt spot... Very common on that control board... If that checks out, set it to cool and meter for voltage to the compressor- 120VAC between the terminal marked COMP (which is J8) and the J7-9 pin on the white connector adjacent to the COMP, LINE, and DEFR terminals.

Ok, yeah has a burn smell and mark towards top of board on green resistor on board. No power showing on j8 and j7-9. Only power coming in on 3 prong connector next to white one.

Did you disconnect the control board, remove it from the recess, and look at the solder-side of it?

[remunguia1]

No just a visual inspection and test.

[Hiroshi]

The burned spot I mentioned will be on the back side of the board, you have to remove the board and look at the solder side...

[remunguia1]

Yes, could it be a bad board?

[Hiroshi]

Is it burned?? If you follow my lead we will figure it out...

[remunguia1]

There is a burnedspot there. No power on j8 j7-9.

Burned resistors on the board are an indication that the board may have been taken out by a bad fan. Looks like that one has a shaded pole condensor fan by the compressor that you can test by applying 120v to terminals. The evaporator fan is a brushless dc fan that you can test with a 9v battery. You should be able to google test fan with 9v battery and find a video. If a fan took out the board you will want to find and replace it before installing a new board.

Will do sir. Thanks! So then I would be able to test evaporator fan with a 9v. Battery? Good to know.

Oh and the fuse on the board is still good! I tested it. I wonder why it didn't blow to help save the board?

the circuit board will always fail in time to save the fuse, it's a rule of thumb...
