Dryer wont start because, even though the door is closed, it reads it as open. The Main Contro Board was replaced and the same thing still happens, any suggestions as to what could be causing this issue?

Hello, if you have changed the main control then the only thing left would be the wires or the door switch. do you have an error codes?

  • Hello do you have any error codes below? I have a technician diagnostic sheet link below. E31 E32 E42 E51 E52 E53 E54 E61 E63 E64 E65 E66 Fault Contact Sensor frequency too high Contact Sensor frequency too low Door Sensing failure Motor Relay failure Motor Fault – motor stopped or not starting Motor Centripetal Switch Failure Motor Sensing failure Heater Relay failure Heater to Earth Ground Heater Open Circuit High Limit Thermostat trip count too high Thermal Limiter Open Circuit Possible Fault Conditions Electronic Control Board defective or foreign object interfering with contact sensor Electronic Control Board defective or foreign object interfering with contact sensor Electronic Control Board defective Motor Relay stuck open or closed; Wiring defective Motor overheating; Laundry load too heavy; Low power supply; Motor, or Wiring defective Motor Centripetal Switch, Electronic Control Board Defective, or wiring defective. Electronic Control Board defective Heater relay stuck open or closed; Wiring defective Heating element or wiring defective Heating element or wiring defective High vent restriction, High Limit Thermostat defective or Inlet Thermal Limiter tripped (Electric Model only) Outlet Thermal Limiter tripped Inlet Thermal Limiter tripped (Gas Model only) or wiring defective Possible Solutions Check Contact Sensor and wiring. If no problems are found with Contact Sensor, replace Electronic Control Board. Check Contact Sensor and wiring. If no problems are found with Contact Sensor, replace Electronic Control Board. Replace Electronic Control Board. If motor runs continuously with power applied check for short circuit across motor relay (RL2), or L1 applied to motor relay output (J3-1) with cycle stopped. If motor does not start when “start” key is pressed, check for open circuit between L1 and motor relay connection (J3-2). If no wiring problems found, replace Electronic Control Board. Remove any load from dryer and check if drum turns freely by hand. Check L1 power supply voltage, motor wiring, and motor thermal protector (if motor thermal protector has tripped, it may take up to 30 minutes to reset). Check wiring. Check if Motor Centripetal Switches are stuck in open or closed positions. Replace motor. Replace Electronic Control Board. Replace Electronic Control Board and retest. Check for short circuit across heater relay(s) (RL5, RL6, RL7) or L1 applied to heater relay output(s) (J5-2, J7-1, J7-3) with cycle stopped. Check for open circuit between L1 and heater relay connection(s) (J5-1, J5-3, J7-2). If no wiring problems are found, replace Electronic Control Board and retest. Check heater coils and connections for short circuits to the cabinet. Replace heater and/or wiring and retest. Check heater coils and connections for open circuits. Replace heater and/or wiring and retest. For Electric Model, check Inlet Thermal Limiter for continuity. If Thermal Limiter is open, check for evidence of high temperature event and any resulting damage. If no further damage is evident, replace Thermal Limiter. If no problems are found with the Thermal Limiter, check exhaust vent system for air blockages. If no problems with vent restrictions, check/replace High Limit Thermostat, and retest. Check Outlet Thermal Limiter for continuity. For Gas Model, also check Inlet Thermal Limiter for continuity. If Thermal Limiter is open, check for evidence of high temperature event and any resulting damage. If no further damage is evident, replace Thermal Limiter and retest.

Check resistance of Outlet Control Thermistor, and check wiring for open circuit. Resistance should be between 4.9K Ohm and 6.2K Ohm at room temperature (68-77° F or 20-25° C). Replace Outlet Control Thermistor and/or wiring and retest. Check resistance of Outlet Control Thermistor, and check wiring for short circuit across Thermistor connections. Resistance should be between 4.9K Ohm and 6.2K Ohm at room temperature (68-77° F or 20-25° C). Replace Outlet Control Thermistor and/or wiring and retest. Check connections between Electronic Control Board and Interface Board. If no wiring problems, replace Electronic Control Board or Interface Board. Check if correct Interface Board console and Electronic Control Board are installed. Replace appropriate hardware. Check if correct Interface Board and console are installed. Replace Interface Board and/or console. Replace Electronic Control Board. Replace Electronic Control Board. Check frequency of line voltage. Check amplitude of line voltage. Check amplitude of line voltage. Check wiring at terminal block for L1-N-L2 wired incorrectly. Replace Electronic Control Board. Check vent restrictions and resistance values of Exhaust Control Thermistor and Inlet Control Thermistor. Check vent restriction, Contact Sensor, and resistance values of Exhaust Control Thermistor and Inlet Control Thermistor Check buttons for activation when pressed. Replace console or Interface Board
  • There is no error code displayed, it just says ”door open”. Switches were replaced as well and still nothing. Tech says he will replace thermal fuse but if that doesn’t work he doesn’t know what else to do. Any other suggestions?
