Gerry H for Model Number dv448aep/xaa My dryer is not drying. Checked with ohm meter all heating elements and are within spec. of trouble shooting guide. ( thermistor, thermostat 1, 2, 3. and hi temp. It says to check membrane switch but cant find it. Where is membrane switch and what should it ohm.
Answer Hi Gerry. The main power control board is part # DC92-00123A. The heater relay has to close and send the 120vac to one side of the element for heat. The motor part # is DC96-00791A. It has to close the internal centrifigul switch to send the other half 120vac to the heater for 240vac proper voltage. This will only happen when the motor sw. closes and all thermostats are closed and the thermister on the blower hsg. controls the on/off temp. swing of heat. However the motor is no longer availiable. Please call APP Call Center 1- (877)-477-7278. Thank you. Read More... Answered by AppliancePartsPros.com | Friday, September 16, 2011
