<<<In diagnostic mode, I get the following code: 18:F0 / U01.>>>
Software ID number---not important.
I would check the voltage at the Terminal Block (220v at both sides)
Check for burned wiring at the Terminal Block.
By-pass the Thermal Limiter AND the Hi Limit Thermostat---plug in and test-run the dryer.
If heater works---replace both (6931EL3003D
) and (6931EL3001F
Re-Verify that the Motor Centrifugal Switch is indeed "good"...
Pull plug off motor
On the *belt & pulley* side of the motor---there's a *black ring* on the motor shaft.
This ring slides inward when the motor reaches speed.
Using your finger---slide the ring towards the blower-slide of motor and hold it there.
Measure continuity at the Motor plug connector on the side of the motor (centrifugal switch)--check for continuity on the farthest-to-the-left pin and the farthest-to-right pin (none of the other motor connector pins matter for this test). It should show continuity---if not---replace Motor.
