Checking Heater Solid State Relays
1
Disconnect and lockout the main power supply.
2
Open the electrical enclosure.
3
Locate the regeneration solid state relays.
Refer to the wiring diagrams that
came with your dryer.
4
Turn power on to the machine.
5
Start the dryer.
6
Measure voltage across the high voltage connections using a voltmeter.
When relay is energized, as indicated by the LED (green) voltage should be
read 0 (zero). When relay is de-energized, LED off, full voltage should be
measured across the relay. When relay is off, if voltage reads zero, relay is
bad and needs replaced. Repeat this procedure for each relay.
