Question about GE Profile JS998 Kitchen Range
Burners still work, but display went blank 2 mornings ago. Oven 1.5 years old. Was working fine (except clock was slow), and then just quit working. Breaker is fine and unplugged for a while and still does not work. Handyman looked at fuses and wires in back, but were ok. He did not feel comfortable looking under top so problem may stem from there. Anyone else have this problem? Have you been able to fix? Was it costly?
I have a GE GS998S0K3SS slide-in range with Trivection oven. The display stopped working and oven controls were nonresponsive. Electric cooktop was still working.
In my case the problem is the Main Power Board, part number WB27T10551, $340 at AppliancePartPros.
Turn off the breaker
Remove the cooktop control knobs.
Remove the three plastic and one brass holder that are behind the control knobs.
Lift the faceplate, remove the electric connector, set faceplate aside.
Remove the four screws holding the panel.
Lift the panel, disconnect all the connectors, set it aside
Remove the ten silver screws holding the black trim that the control panel was mounted on. There are five at the top and five underneath that are visible when you open the oven door. Set aside the black trim.
Remove the two black screws holding the cooktop in place. One front left, other front right.
Set aside the cooktop.
The main power board is the large PCB with heat sinks on the right towards the rear. To verify it is broken you need a voltmeter.
At the rear right there is a black, white, and red wire, plugged into ports J101,J102, J103. Disconnect all three.
Turn the power back on.
Verify 120VAC between J101 and J103 wires
Verify 120VAC between J102 and J103 wires.
If this test passes, turn off power, reconnect wires, disconnect connector J3 (front left of board). Turn power back on.
Verify +12VDC between J3 pin 1 and pin2
Verify +5VDC between J3 pin 3 and pin 2
Verify -14VDC between J3 pin 5 and pin 2.
If tests fails replace the board and reverse the disassembly directions.
The board is sitting on 12 hold-down pins. I used a small diameter deep-well socket to squeeze the pins and gently lift the board. Getting all the pins to line up under the new board is a pain. Gently push the new board down into place.
