Blower Circuit Faulty
The blower circuit controls the electricity flowing to the blower. It consists of a power cord, wiring
harness, snap disk, and rheostat. This allows the blower to be variable speed and shut down
automatically when the heater cools. The two symptoms below detail the troubleshooting steps for
the blower circuit (the blower circuit is 115V A.C., not a D.C. millivolt system).
Disconnect the power supply before servicing electrical components.
Blower is stuck on High
This indicates a defective rheostat. Replace the rheostat (see the directions below).
Blower does not turn ÒONÓ
The blower will not start until the heater is up to temperature - approximately 15 minutes. This time is
longer if the flame is turned to low.

Check the outlet to make sure it is supplying power.

With the power cord removed, check the wiring using the diagram below as a guide. Use
a multimeter to check continuity between the wires. Check for loose connections or
burned wire insulation. Replace any damaged component.

With the power off, access the blower snap disk (it is found on the back side of the firebox
on stoves and inserts and underneath the burner pan on fireplaces. Disconnect the two
wires leading from it and ÒjumpÓ them together with a wire that has two male quick-
connects attached. This will bypass the snap disk. If the blower then turns on when the
power is restored, the snap disk is defective and should be replaced.
