GE side by side refrig. had elevated temp. in refrig.
Freezer evaporator iced up. Checked defrost heater(single heater) which measured 26 ohms(assumed good). Checked defrost thermostat in freezer, which was approx. 0 ohms cold.(assumed good). Defrosted evaporator with hair dryer. Posted a troubleshooting question on this website, received a reply to replace the main control circuit board(GEH WR55X10942), which I did on Oct. 3. I placed a digital Wattmeter in refigerator AC power cord to monitor AC current drawn by refrigerator. Since installing new control board I have not seen AC power on wattmeter in the 500 W range, indicating that freezer is in defrost cycle. When compressor runs, power drawn is approx. 150 Watts. Refrigerator is maintaining 35-40 deg. temp. HOW can I force freezer to go into the defrost cycle, to verify that the new control board is functioning properly and freezer is defrosting ??? I have not pulled rear interior panel of freezer off since Oct. 3, to check for evaporator ice build up.
Thanks, Rick

Rick, Heres a quick easy test for the defrost system :
[LEFT][COLOR=#000000]“Pull the back motherboard cover and locate the 3 pin power connector. Remove the connector and place a wire jumper between the connector mating pins marked line and def. Plug fridg in, if you fail to get defrost action, you probably have a bad evaporator thermostat clipped to the evaporator. If defrost action, replace the motherboard”[/COLOR]
[COLOR=#000000]If all checks are OK, replace the control assembly.[/COLOR][/LEFT]

order a cn101 110 v timer from china and wire it into 110 v. run 2 wires from switch side of timer to j8 and j9. you now have a working defrost timer.

I do not think this “timer” idea is a proper solution. The problem is, the Compressor and the Evaporator Fan should be turned off whenever the Defrost Heater is turned on. How can a simple timer accomplish this?
