my dryer has not started when using normal start buttons, but I figured out that if I 1st push"air fluff", then press timer to 19 sec. ,dryer will start and all buttons will then work. I've been doing this for months, but now 8.8 code is showing, and I can not bypass it to start dryer. Also cannot access service mode,etc.,as a result of8.8. After much internet research, it appears I should be ordering either a)electronic control board 33003208,or b)led console assy 22004444. I have used your site and already checked 1)voltage 2)ground 3)ribbon from control board to control console. All 3 are ok. Do you have a solid recommendation which part to order,or should I have a service repairman check it out. Since parts are not returnable once open, I do not want to order both.
Answer Hello Roger. It sounds like a control board 33003028 issue you are describing. Also, if you order through us, and the part is not needed, you can return it. There is a 365 day return policy. Even on electrical parts.
I have trouble shot all areas as recommended. Conclude that I have an Electronic Control Board issue and a replacement with part number AP4044079 is required. Also have an issue with Thermistor in that it reads very low olhm in relation to those on dryer repair trouble shooting sheet. My question is can a faulty thermistor, thermostat or sensor bar cause a current spike to the control board that would fry it? I'll order parts tomorrow after receiving your input. Thanks Casper
Answer Casper, A weak thermistor or sensor bar circuit, should't create an issue for the control board. They are a resistance circuit, and if any voltage at all is produced, it's very low, and would not damage a control board. A thermostat or element on the other hand could damage a control board, they carry the 220/240 VAC, but it would be to the heater circuit relay, which could be pretty apparent, the board or relay would usually show signs of the short(burnt or melted components). You may want to re check the thermistor bulb for debris or corrosion, and check the resistance across the terminals with the wires off. reconnect the wires and check for the same resistance at the thermistor connection at the control board (conn J4 pin1 and 2, pink wires) The reistance should be identical and within 10 % of the specific range for the temperature tested at (room temp, or approx. 78 dgrs.) If the reading is drastically different or low, then the issue is the wiring or the thermistor. If the readings are all in range, then the issue is in the control board. Thanks and Good Luck
