To Test Gas Valve Coils
(Gas Models)
1. Remove disconnect blocks from gas valve coils.
2. Set test meter to read Ohms and put meter
probes to terminals shown in Figure 40,andin
the following chart.
SILICON CARBIDE IGNITION:
Coil Tolerance Readings
SILICON NITRIDE IGNITION: Both coils should
read between 2400 - 2800 Ohms.
NOTE: If meter registers any other readings than
those listed above, the respective coil(s) should be
replaced.
Meter probes to terminals: Meter should read:
Holding Coil – Terminals 1 & 2 1365 ± 25 Ohms
Booster Coil – Terminals 1 & 3 560 ± 25 Ohms
Secondary Coil – Terminals 4 & 5 1220 ± 50 Ohms
