Older Kenmore Elite, fires up when you hold the start button but stops once you let go.
Went through all of the diagnostics and everything checks out ok. Bypassed all the switches and exact same performance. Replaced the circuit board, exact same, replaced the motor and same.
Test mode passed.
Thermal fuse no resistance. Also bypassed it.
Door switch turns light on and off when toggled.
Thermistor resistance 11.7k at 70 degrees. Shorted leads and control board gives three beep warning.
Belt switch bypassed, connected directly to motor lead.
Bypassed thermal cut off and high limit thermostat
Relays triggering and replaced just to make sure
Heating coil at 10ohms, no short to chassis
Replaced motor and CF switch
Replaced circuit board
When holding start button, unit runs and heating relay clicks on and off fairly quickly and unit heats. I assume the circuit board is triggering the relay bit then resetting because some condition is not met, yet all tests ok.
Your assistance is greatly appreciated!
