What to do if your water heater doesn’t ignite?
If the Thermopile output is less than 350mV, you may remove it from the burner and clean off any corrosion. If the Thermopile output is adequate, the fault lies within the Gas Control Valve. Unfortunately, there are no user-serviceable parts in there, so you would need to replace that entire assembly.
Why does my Atwood water heater not ignite?
There are several issues behind why your Atwood Rv water heater doesn’t ignite. In this chapter, we break down every possible cause and provide the solution as well. A thermocouple is a device that senses the heat of a pilot and lets the gas flow to the burner.

Will my gas water heater work without electricity?
Tankless water heaters do not work without electricity. Even natural gas and propane-powered tankless water heaters need an electrical supply to function, as they depend on a digital remote or PC board to sense the flow rate of the water.
How does the ignition of a water heater work?
A millivolt ignition system is a method of igniting gas furnaces, gas logs, and gas-fired water heaters. They utilize either a thermocouple or thermopile. These devices, when heated, provide the millivolts to a pilot solenoid valve in a gas valve. Thus the pilot light burning to heat the thermocouple or thermopile.
What to do if your water heater is not heating?
If the pilot does not light, the water heater will not heat. Sometimes, carbon deposits can build up on the pilot and eventually create a restriction. …If the pilot is restricted, try removing it and clearing it with a stiff brush and/or compressed air. If the pilot cannot be cleaned, replace it.
