Why does my vent free heater keep going out?

Why does my vent free heater keep going out?

The heater won’t operate properly if the pilot flickers, is too weak or goes out, and the cause could also be blockages in the pilot tube. Another cause of a weak pilot is a faulty thermocouple. It’s a heat sensor placed next to the pilot flame that signals the gas valve to stay open when the flame is burning.

How do you bypass a thermocouple?

To bypass the thermocouple:

  1. Move the tilts switch wire aside.
  2. Remove your thermocouple from the heater using an 8mm wrench.
  3. Pull the valve housing aside using your 13mm socket wrench.
  4. Remove the valve using your pliers.
  5. Put your thermocouple back into position.

Will a pilot light stay lit with a bad thermocouple?

The job of the thermocouple is to keep the pilot lit. It does this by sending a tiny electric current to a sensor on the gas valve signaling the valve to stay open. Nothing lasts forever, and when the thermocouple wears out, the pilot won’t stay lit and your appliance won’t work.

How hard is it to replace a thermocouple?

Thermocouples are designed to detect a pilot light’s loss of heat and close the gas valve to prevent a gas leak. Replacing a thermocouple is a relatively easy fix that can take less than two hours.

What does a bad thermocouple look like?

Before jumping to the conclusion that the thermocouple is at fault, look at the pilot flame. If it appears small and has an orange-yellow tinge, it may be too weak to heat the thermocouple. The likely problem, again, is an obstruction in the pilot tube.

Can I replace a thermocouple myself?

The No. 1 cause of pilot lights that won’t stay lit is a worn-out thermocouple. It’s easy to replace and a new one costs $5 to $10. Rather than trying to unfasten the thermocouple inside the water heater’s burning chamber, it’s easier to remove the whole burner and thermocouple assembly.

What are the symptoms of a bad thermocouple?

If you can’t get the flame to light at all, and you’re sure the gas is on, there’s probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that’s the sign of a thermocouple malfunction.

Does cleaning a thermocouple help?

Yes, you can clean a thermocouple, but the task must be done with a light touch. Remove the thermocouple from the process assembly, using a steel wool or emery cloth, lightly clean the tip removing any build up. Cleaning a thermocouple is not a fix for an issue, such as inaccurate readings.

Can you bypass thermocouple on furnace?

Realistically, you have just disabled the thermocouple, but you can also reach in and unclip it from its holding bracket where it meets the pilot light. In most cases it will be held on with a gravity clip, but some are held on with a screw that must be removed with a small screwdriver.
