Why does my pilot light go out when I release the pilot light knob?
Why does my pilot light go out when I release the pilot light knob?
The most likely of those is that the thermocouple needs to be replaced. The button you press to light the pilot bypasses the thermocouple. When you release the button, the thermocouple ensures that unburned gas doesn’t get released by shutting off the gas when it’s not heated by the burning pilot light.
What causes a boiler to not stay lit?
If it’s not staying lit though, then you’re probably dealing with a thermocouple issue. The thermocouple of a boiler system is a long metal wire that acts as a heat sensor for the pilot light. If the pilot light goes out, then the electrical current stops, and the gas valve closes.
Why has the flame gone out on my boiler?
If the pilot light on your boiler has gone out, the cause is usually debris blocking the jet. Even a small spec of dirt can block it, cause the pilot light to go out, and then the boiler won’t re-ignite. These jets are cheap to replace, but they can usually be removed, cleaned and reinstalled to fix the problem.
What does it mean when your pilot light wont stay lit?
thermocouple
If your pilot light won’t stay alight, it might be the thermocouple. Sometimes dust buildup collects on the thermocouple and blocks the sensor. Try cleaning the thermocouple and then relighting the pilot light. If it continues to go out, the thermocouple might need to be replaced.
How do I make my pilot light stay lit?
How to Light Your Furnace’s Pilot
- Make sure the thermostat is in heat mode.
- Locate the pilot valve.
- Always turn the valve knob to the off position and make sure to wait at least several minutes for any residual gas to clear away.
- Get your match ready.
- Once the pilot stays lit, turn the pilot valve to the on position.
Why won’t my pilot light stay lit on my gas heater?
If your pilot light won’t stay alight, it might be the thermocouple. Sometimes dust buildup collects on the thermocouple and blocks the sensor. Try cleaning the thermocouple and then relighting the pilot light. If it continues to go out, the thermocouple might need to be replaced.
How do you reset the flame on a boiler?
If your boiler has an ON/OFF/SELECTOR switch:
- Open the fascia display.
- You may see an error code, or (if you have a boiler without a display screen), a flame failure light.
- Turn the selector switch to the R (‘reset’) position.
- Hold for five seconds before releasing.
How do you reset the flame failure on a boiler?
To reset the boiler, turn the selector switch to the R (Reset) position. Hold for at least 5 seconds and release. The fault code will be replaced with the boiler’s current temperature. At this point on a neon indicator boiler model, the flame failure light will stop flashing and will be replaced with the burner light.
