Neither of the lights on the Thermostats will illuminate.
ANSWER Bob, You'll need to check for power from the Electronic Defrost Control Board 4388932. At the control board you'll need to check for 120 VAC across blk pin #1 and wht pin#6 in the harness. Then check for 120 VAC across wht pin#6 and orhg pin#4, power out to the thermostat(s). At the thermostats Freezer control should have 120 VAC from chassis ground to orangepin#3, and with the freezer thermostat in the "on" position 120VAC on orange/black pin#2 to chassis ground, At the refrigerator control there should be 120 VAC on the orange/black wire pin#2 to chassis ground If you have all the voltages, you'll need to replace the thermostat(s). Thanks
