After dryer completes timing system (say it set for ten minutes) the dryer does not shut off but continues and the ten minute digital number disappears and in its place are zig-zig displays. The heat continues as well.
Answer Hello Ted,
This sounds like the relay on the control board is stuck. After looking it up for you, the manufacturer says: Will Not Shut Off
• Check Membrane Pad.
• Check Electronic Control Board.
• Short in sensor circuit.
The zig-zag in the display eliminates the membrane switch and the sensor. The electronic control board 35001153 is the most logical deduction.
Our dryer is showing FE in the display and incoming current is 120 on each line. 238 both lines. Heat is working. Drum will turn in system check mode. Dryer will fault out even if not turned on as long as it is plugged in. Is this board the next thing to check? Thanks?
Answer Hi Dennis. Since this is a power frequency fluctuation code then remove the power cord from the unit. Look at the terminal block part # 279320 for any looseness of the terminal studs. Inspect the dryer cord to see if the male ends as well as the eyelet end's are burnt or frayed loose. Inspect the power cord as it comes into the unit control board. Make sure all connections are tight. Have a Professional Electrician to inspect the dryer outlet and breaker for loose wire connection there as well. A floating neutral or a hot leg can cause funny issues. Thank You.
