Original motherboard GE PTS25LHPARBB Original motherboard "fried"..Replace it with New replacement board (different number). Temperature readouts on the control panel are -4 when set at 0 (Freezer) and 32 to 35 when set at 37 (Fresh Food) The original was true to settings. What gives?

I had similar problems with my GE and had to replace the control board. Solved the problem but when I examined the failed board the main filter capacitor was bad whic I replaced. I do not know if it fixed it I never put it back in.

Yup Yup, been there. We had to replace the control board on ours. We are lucky enough to have a repair service tech in town that came by and diagnosed this (cheaply since he didn't really do anything), gave us the part number and where locally to order the new control board. Easiest way is to contact the manufacturer to order a new one. If its the exact same problem, the oven wont hold temperature, will start to heat up then gives the code. The board is very easy to replace, takes less than 30 minutes.

Your refrigerator uses the common GE WR55X10942 control board. On most models you can just swap out the control boards. Some models require a few additional steps, you will have to check your serial number to see if that applies to your model (see instruction sheet included with the control board).

First unplug the refrigerator.

On the back of the refrigerator, there is a panel. Remove the screws and the panel cover.

Unplug wires from the old control board (note where the wires go), and plug them into the new control board.

Plug refrigerator back in and test out.

How to replace WR55X10942 control board

replace the main board located behind the unit behind a silver colored panel at the lower side new board number is a g.e.# wr55x10942

you will need to replace the main control board located on the rear panel behind an access panel,this board controls all temps and digital readouts,when the readout goes dark this board is the culprit

Through experience I have found that this is generally not the small board in the dispenser area, but a problem with the motherboard (behind the refrigerator). Replace the motherboard.

You have a bad main control board . This board , is located behind the refrig , behind an 8 " X 10 " small panel . It is easily replaceable . If you had given the model number , I could have given you the part number , so be sure to take the model number with you , or call GE , as it could possibly be replaced under warrenty .

Sounds like you have a bad main control board . The original pt # is WR55X10552 . The replacement board is WR55X10656 . Your original board , is on a recall list , and GE should come out and replace under an extended warranty .

I think is just the display board next to the cold control.

That would be a problem with your control board. It probably needs a few capacitors and a relay replaced and minor circuit board repair.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week with a one-year guarantee.
