Why COZY DVCF403C-H standing pilot won’t light or stay lit?
If the pilot won't light or stay lit, there might be air in the line, so bleed the line. The thermocouple could be defective, so replace it. The pilot flame might be too low, so adjust it. Also, the manual reset switch might not be engaged, so depress the red button on the switch.
Why my COZY Wall Furnaces burner won’t turn on?
Several issues could prevent the burner from turning on. First, ensure the gas valve is in the “on” position. Check for 24 Volts to the valve from the transformer. Verify the wall thermostat is functioning correctly. Ensure there is 115 V line voltage. The gas valve itself may be defective and need replacement. Lastly, check if the manual reset switch is engaged by depressing the red button on the switch.
Why won't my COZY DVCF403C-H burner turn off?
The burner might not turn off due to several reasons. It could be a defective or damaged thermostat wire or the thermostat itself; this can be checked by removing the wire from the valve terminal. If the valve goes off, replace the wire or thermostat. The thermostat location might be incorrect, so follow the installation instructions and check the location. A defective or sticking valve can also cause this issue, requiring valve replacement. Finally, excessive gas pressure could be the cause; contact the utility supplying gas in this case.
