Question and Answers

Q:

kenmore dryer motors 4 each now vibrait and noizy 41784072300

A:

Thank you for your question and I understand your concern.

We do not have any reported issues with the motors for your dryer. Based on you symptom and details, it sounds like the motor is running on 220 volts instead of 110. If it makes alot noise and vibrates when bench testing, I suspect the voltage supply to the dryer or motor is not correct.  You did not supply any voltage measurements or indicate where you made the voltage measurment so I can't confirm if you have it wired correctly or if your getting the proper voltage. The dryer needs to have 220 volts connected to it but the motor operates on 110 and the heating element requires 220. At the terminal block at the back of the dryer where the power cord is attached should measure 110-120 volts when measuring from the center terminal to each outer terminals. The voltage should measure 220-240 when measuring across the two outside terminals.
 
The voltage supply to the motor is measured across M4 (Gray wire) and M5 (White wire) which should measure 110-120 volts when the motor is running. Terminal M2 (Black wire) and terminal M1 (Yellow wire) is the Line 2 voltage feeding 120 to one lead of the heating element. When the motor starts, contacts M1 and M2 closed to complete the line 2 voltage to one terminal of the heating element. The L1 voltage supply is completed to the other terminal of the heating element when the heater relay closes. When L1 and L2 is supplied to the heating elment it will begin to heat.

I hope this helpful. If you need any further assistance, reply with voltage measurements and where you made the voltage measurements.

Q:

Why won't my Kenmore dryer 41784072300 turn on and the message L:OC appears on screen and it beeps?

A:

According to your description, it sounds like the CONTROL LOCK is enabled. Press and hold the LOCK icon until LOC is no longer displayed. This should fix your problem.

Q:

My Kenmore dryer Model 41784072300 stopped mid cycle, and now will not restart.

A:

The PR:U that you see in the display is likely PA:U which indicates that the control is stuck in a PAUSE mode. If you are not able to press the STOP/CLEAR button a second time to clear the control (or press the START button to resume the cycle), then it is likely that you have a failed control pad on the dryer. To fix this type of failure, the membrane touch pad will need to be replaced. I recommend calling a service technician to diagnose and repair this type of problem.
