One of the gas-powered water heater’s essential components is the pilot light, which ignites the gas that heats the water. If you have an older unit, chances are it’s still using a standing pilot where there is always a continuous flame. If the pilot light won’t stay lit, your heater won’t be able to warm up the water, disrupting your daily routine.
When this happens, don’t hesitate to contact Keeley’s Plumbing immediately for water heater repair in Wheaton, IL. To help you deal with this problem, it pays to learn the culprits behind it:
1. Faulty Thermocouple
A thermocouple is a safety device that helps prevent gas leaks by sensing when the pilot light gets lit. If it gets dirty or malfunctions, however, it shuts off the gas supply, causing the pilot to go out. Enlist professional water heater services to have the thermocouple cleaned or replaced and get your unit up and running.
2. Dirty Pilot Tube
The pilot tube delivers gas to the pilot light. If it is blocked by debris, the flame will go out. This is a common problem in a water heater installation, and you can solve it by cleaning the tube with a slender needle.
3. Flex Tube
The flex tube connects the gas controller and the burner, which houses the pilot light. When this part of your traditional or tankless water heater gets clogged or damaged, the gas won’t reach the burner for combustion. To fix this, straighten any curves on the tube and look for signs of gas leaks. This is a serious cause of concern, as such leaks can pose safety hazards to your household.
4. Main Control Valve Issues
If you have checked the thermocouple, pilot tube, and flex tube but don’t see any red flags, the problem might lie in the main control valve unit. This component regulates the heater’s gas and water pressure.
Once it gets faulty, it can suddenly stop the gas supply and cause a flickering flame. Telltale signs of a broken main control valve include when the water is hotter than your set temperature and the pilot button doesn’t pop up after pressing.
