Are you wondering why wont my water heater stay lit? No more wonder you have arrived at the right page. When a gas water heater doesn’t remain lighted, it might be due to a faulty control thermostat. That valve regulates the gas flow to the piloting unit.
The thermostat inlet valve may be defective if the light is not lighted and the heater thermocouple is fine. Debris can build up inside the pilot tube, obstructing the gas flow. As an outcome, the pilot’s fuel supply is insufficient to keep him illuminated.
If somehow the pilot won’t light, this is a potential explanation. The trouble with the thermocouple is pretty standard, and this element is frequently to blame whenever the water heater pilot continued off. This gadget detects an electronic current from the heat of the pilot light to identify whether it is on or off. Continue to reading to learn more!
Why Water Heater Won’t Stay Lit
Probably no one likes any damage with their gas water heaters, whether you’re accustomed to showering and doing household activities with heated water. However, events may not go as planned, and the water heater pilot light might not even function appropriately at instances. You’ll know you have a defective water heater if the pilot light will not light up. These reasons will help you understand why wont my water heater stay lit.
#1. Faulty thermocouple
Most of the frequent reasons your water heater won’t remain lit is a faulty thermocouple. If you have got a gas-fired heater, you should know that such a standing pilot ignites the primary burner. This thermocouple controls the fuel supply towards the pilot unit, which is governed by the main pipe valve. To guarantee gas flow to the water heater pilot light. Because a defective thermocouple can’t detect the flame, the valve won’t get the high voltage it needs to allow the gas to flow to the pilot assembly. This will turn off the gas supply as a safety precaution rather than illuminate. Here are common water heater thermostat problems.
#2. Thermocouple that is filthy
Sand particles will get in the line and interfere with the thermocouple’s output. A thermocouple is fooled into thinking the pilot is already out, as well as the gas supply is cut off to make things safer. Cleansing your thermocouple is a simple solution to this problem. Ensure the valve is turned off not to leak when you begin cleaning. The thermocouple may then be found and cleaned.
#3. Bent thermocouple
Some other problem that might cause your thermocouple to malfunction is bending. A thermocouple could be twisted to the extent where the heat signal generated by an electric current is lost. A thermocouple will not receive the heat message if it is bent too far away from the pilot, and the heater pilot light will not stay lit. To correct this issue, you must align the thermocouple. Assure it bends back toward the pilot, and the flame hits it just a little. Let it rest for at least 5 minutes before handling it to prevent burns. We can also employ a safety gadget to safeguard ourselves in this situation.
#4. Broken thermocouple
If you have a damaged thermocouple, the gas hot water tank will most likely not light up. Many heaters, regrettably, have this issue occasionally. Disconnect the thermocouple, then examine it with a perfect multimeter to see whether you’re working with a broken one. When trying to eliminate the thermocouple, be sure the valve is turned off and the thermocouple has had time to calm down. Verify for a voltage supply of less than 25 MV. If this is the situation, you’ve got a broken thermocouple on your hands.
#5. Obstructed pilot tube
Throughout time, dust and dirt develop in the pilot tube, causing an obstruction that can obstruct the gas supply. Whenever there is an obstruction, the pilot will not access the gas he needs to keep lighted. This issue could even prohibit the pilot light on the water heater from illuminating. Users don’t have to be concerned, though, since cleaning a filthy pilot tube is simple.
#6. Faulty control valve
A malfunctioning primary control lever might also cause the water heater pilot light, not lighting. When neither preceding remedies the issue, the issue may be with the thermostatic controller. This is also known as the controller. Although this is a rare occurrence, some people blame it for their heating issues. When you think this is the case, look for other faults with the pilot light and whether they’re the root of the problem. Using a multimeter to check for a defect in the primary control is one method to be positive.
