Clear code, exit mode and start dryer. If problem persists, replace electronic
control.

Remove wires from control thermistor. Measure resistance of thermistor. If
reading is not 50 K (± 10%), replace thermistor. If reading is within 50 K
(±10%), check wiring between thermistor and electronic control. If good,
replace electronic control.

reading is not 50 K (± 10%), replace thermistor. If reading is within 50 K
(±10%), check wiring between thermistor and electronic control. If good,
replace electronic control.
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.
Position cycle selector to NORMAL, temperature selector to HIGH HEAT
and touch START. Measure voltage across terminals on relay RL2 (heater
relay) on electronic control. If meter reads 240V on electric models and
120V on gas models, replace electronic control. If meter reads zero, remove
power from dryer. Disconnect wire going to NO terminal on the relay RL2.
Reconnect power and measure voltage drop between terminal COM on relay
RL2 and neutral. If meter reads zero, wire between incoming line and relay
RL2 is open. If meter reads 120V, check the rest of the heater circuit.
Enter function test mode and perform key (button) test to determine which
button is at fault. Carefully free the key (button) and perform the test again.
If button is free but the key struck code still exists, replace electronic control.
Check for blocked lint filter, blocked exhaust, air leaks around air duct,
broken blower fan blades, worn or loose drum seals, dryer installed in closet
with solid doors or door seal not correctly seated.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
