Mikej for Model Number AEQ8000FS0 11 year old dryer stopped heating after replacing drum bearing and adding new belt - runs no heat for 10 mins then shuts off and flashes three lights at right - error code E5b - no heating (duh!). continuity at thermal fuse, high limit thermostat and element (no breaks). Thermistor reads about 70K Ohm when I can get my junk HFT cen-tech meter to give a reading - should be 50K - but would think this would only make dryer run hotter than it should? Is there a way for me to test the control board? Seems like most of the solutions on tech sheet for error codes are to replace electronic control.
Answer Mike, Here are the steps to take to find out what is going on with the unit. Position cycle selector to NORMAL, temperature selector to HIGH HEAT and touch START. Measure voltage across terminals on relay RL2 (heater relay) on electronic control. If meter reads 240V on electric models and 120V on gas models, replace electronic control. If meter reads zero, remove power from dryer. Disconnect wire going to NO terminal on the relay RL2. Reconnect power and measure voltage drop between terminal COM on relay RL2 and neutral. If meter reads zero, wire between incoming line and relay RL2 is open. If meter reads 120V, check the rest of the heater circuit. Read More...
