VOLTAGE ACROSS:
4 & 1; 4 & 2; 4 & 3: 1. Check for power at ignition module terminals. If 24VAC power is present damper
is working properly.
2. Defective component in appliance after the flue damper.
3. If 24 VAC is not present at the ignition module, look for loose or broken
connections between damper and ignition module.
4. If the connections from damper to ignition module seem proper, replace damper
assembly. If a damper assembly is not available, place the service switch in the
hold open position. This should keep the damper in the open position and allow
the customer to have automatic heat, until a replacement damper can be installed.
