1. Check incoming voltage. Appliances must have 240 volts with a neutral.
2. Check voltage at main relay board at L1 and N just in front of the low voltage
transformer. Should read 120 volts. Refer to picture for voltage test points.
3. If you do not have the voltage at L1 and N check wires and connections at
terminal block.
4. If you have 120 volts at L1 and N then check voltage at main ERC harness
connection coming off ERC clock control. Refer to picture for test points 14
and 15. Should have 22-24 volts AC input to ERC/clock control.
5. If you do not have 22-24 volts AC, suspect the main relay board or main
harness.
