To Test Gas Valve Coils:
Models starting Serial No. ________
1. Remove disconnect blocks from gas valve coils.
2. Set test meter to read OHMS and put meter
probes to terminals as follows: (Refer to
Figure 17.)
a. Holding Coil - Terminals 1 and 2 - Meter
should read 1365 ± 25 Ohms.
b. Booster Coil - Terminals 1 and 2 - Meter
should read 560 ± 25 Ohms.
c. Secondary Coil - Terminals 4 and 5 - Meter
should rear 1220 ± 50 Ohms.
Models through Serial No. ___________
1. Remove disconnect blocks from gas valve coils.
2. Set test meter to read OHMS and put meter
probes to terminals as follows.
3. Connect Ohmeter between black and blue wires
- 120 volt power supply.
a. Reading 567 to 694 Ohms - All coils are
OK.
b. Reading 1100 to 1430 Ohms - Move
Ohmeter to white and blue sensor wires.
4. Connect Ohmeter to white and blue sensor
wires.
a. Reading 1640 to 2010 Ohms - Secondary
coil open - Replace.
b. Reading 630 to 770 Ohms - Move Ohmeter
to red and black igniter wires.
5. Connect Ohmeter to red and black igniter wires.
