Corrective Action
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
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
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
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
