| B. Faulty connections. | B. Measure voltage between valve body and |
|
|
|
| |
|
| solder connection on the rear of the valve |
|
|
| (where the blue wire connects). It should be |
|
|
| no less than 7 mV. |
|
| C. Defective thermocouple. | C1. Ensure that the thermocouple connection |
|
|
| at the gas valve is tight. |
|
|
| C2. Check thermocouple output using milli- |
|
|
| volt meter. Disconnect from valve and read |
|
|
| voltage across wire ends. If the reading is |
|
|
| less than 15 mV, replace the pilot assembly. |
|
|
| C3. If burning NG, check pilot flame to see |
|
|
| that it is impinging on the top of the |
|
|
| thermocouple. Clean or replace pilot for |
|
|
| maximum flame impingement. |
|
| D. Pilot dirty or plugged. | D. Clean or replace the pilot assembly. |
