Key Panel Test - GE JKS10 Technical Service Manual

Model JKP75, PK956, & ZEK958
*If the oven light is not working, make the following
checks:
• Check the oven light bulb.
• The light is to come on when the door is opened―
check the voltage across the light socket. Terminals
should read 120 VAC. If 0 volts, check the jamb
switch and the wiring.
• The light is to come on when the control light
pad is pressed. K11 or K12 should click. Check the
voltage from N to J6-3 (upper) or N to J6-1 (lower). It
should read 120 VAC. If 0 Volts, check the oven light
keypad using the ohmmeter test. If the keypad is
good, replace the control.
**If the convection fan is not running, make the
following checks:
• Check the voltage from terminal J11 3 to N on the
control―it should always read 120 VAC in Convection Bake or Convection Roast modes. The voltage should
also read 120 VAC when the convection fan is running CCW from terminal J11 1 to N (upper) and J11 5 to N
(lower–when specifi ed) and when the convection fan is running CW from terminal J11 2 to N (upper) and J11
4 to N (lower–when specifi ed).
• If the voltage is OK, check the convection fan motor. It should read approximately 15–20Ω at room temp.
Check to make sure the fan shaft is not rubbing on the liner.
• Check the door switch.
• Check the capacitor.

Key Panel Test

Models JKS10, JKP30, & JKP35
Note: The key panel and the electronic control are a single component.
Press each pad on the key panel followed by the Clear/Off pad. If the key panel is functioning properly, the
following should occur:
• Bake, Broil, Timer, Clock, and Cook Time pads – Audible tone plus display showing mode of operation
selected.
• Clear/Off – Audible tone and display shows the time of day.
• Temp, Hour, Min pads – No audible tone. Can only be used after another function has been selected.
