Program Timeout Fault
The drying time has exceeded program time for that cycle.
Press Pause Cancel and SELECT buttons for 6 seconds to exit test modes.
Position cycle selector to NORMAL, temperature selector to HIGH HEAT
and touch START. Check for anything that would extend dry times such as:
no heat, restricted vent, blower fan blade broken or loose, dryer installed in
closet with solid door, or bad connection in moisture sensor bar circuit or
dirty bars. If dryer operates normally but code returns, replace electronic control
I would check the vent system for cleanliness also make sure the outside flap is OK.
You could also disconnect the unit from the vent and run a load to check it. If worried about lint, take a pair of pantyhose, put one leg in the other and attach this to the dryer exhaust. Leave enough room so it can blow out like a windsock.
If error still shows up get it repaired under warranty. |
