Troubleshooting Chart
Symptom Possible Cause(s) Corrective Action
Dryer will not run Defective circuit board 1. First ensure that the breaker supplying the dryer is operational
2. If it is, disconnect the power and remove the dryer cover. Taking
suitable precautions to avoid shock hazard, reconnect the power
and check for voltage at the wire leads
3. If there is power and the dryer will not run, replace the circuit board
Dryer cycles by itself,
runs all the time, or is
not sensitive enough
Defective circuit board 1. Ensure that there is no obstruction on or in front of the infra-red lens
2. Disconnect the power. Remove the dryer cover and the screws
holding the circuit board. Ensure that there are no obstructions
between the infra-red “eyes” on the circuit board and the lens
3. If the problem persists, replace the circuit board
Elements get hot but
the fan motor does
not turn
Defective fan Defective
motor
1. Disconnect the power. Remove the dryer cover and check for
obstructions in the fan housings
2. Damaged fans must be replaced
3. If there are no obstructions, replace the motor
Fan motor runs but
the element does not
get hot
Loose or damaged
wires or defective
element
1. Disconnect the power and remove the dryer cover. Check for loose
or damaged wires. Remove the access cover on the blower housing.
Check the element for signs of burning or breakage. Damaged
element must be replaced
2. If the element does not appear damaged, disconnect it at the circuit
board and check for continuity across the two element wires. An
open circuit indicates damage to the integral temperature limit
control. If this is the case, replace the element
