Moisture Control Heater Troubleshooting
Take resistance reading between GF2 P1-2 and GF2 P2-6.
•
Resistance should be 1400 - 1800 ohms.
•
If the Duct Heater is Open, resistance will read ≈4800 ohms.
•
If the Filter Heater is Open, resistance will read ≈2400 ohms.
If resistance checks are OK:
Run Service Test 65 - Ice Box Duct Heater Test
•
Ensure LED display shows “on”
•
If LED display does not show “on”, replace GF2 board.
If all checks are OK and problems persist:
Run Service Test 88 - Ice Box Air Duct Heater Activation Mode
This will turn the heaters Full On.
•
Use up or down arrow to change activation mode to “01”
•
Press the “Icemaker2” key to confirm selection.
