To Check Ignition Control Assembly
Remove fuse cover and check fuse (70,000 to 200,000 Btu models only).
If fuse is blown replace it with a GMA-6.5A fuse part number 113752-01.
Disconnect motor red and white wires from control.
With Ignitor wires disconnected, attach voltmeter leads to the ignitor terminals (labeled IGNITOR).
Use the 0 to 200 V.A.C. scale.
Plug power cord into a grounded 120V/60 Hz outlet. Meter should read 120V(rms) for approximately 10 seconds. If voltage reads 0 or stays at 120 for more than 10 seconds, the control is defective and should be replaced.
DO NOT LET ANY PORTION OF YOUR BODY TOUCH ELECTRODES OR PLUG, DUE TO HIGH VOLTAGE.
