Hello,

I've been fighting defrost issues on my fridge. Every week or so I need to run forced defrost mode to melt the ice off of the evaporator fins. The freezer is working well but the fresh food area is not cold enough. I replaced the defrost thermostat, the heater coil gets hot and is working well. When running service test 3 (evap/freezer fan test) the fan starts to spin, then immediately stops and starts to hum. Turning this fan on/off after the initial on/off test it will not spin at all, but just hum. The fan turns on and runs when out of service mode.
I replaced the Jazz board but the fan still does not spin when activated via test mode. I'm stumped. I though it was the Jazz since the fan spins when not in service mode. Maybe a bad evap/freezer fan? All other tests pass.

Jazz board and fan needs to be replaced and make sure you program the new jazz board
