Hold in your pilot button, then push the spark button repeatedly to light your pilot. Once its lit, hold that pilot button in for 30 seconds to heat your thermocouple. once its heated, release the button, and slide the slider to burner position. Turn on hot water fixtures to get the unit to light

I have an Atwood G6A-8E water heater. It stopped working last year so I took it to Camping Wprld. Their R&I'd the tube and igniter. He cleaned to tube and adjusted the igniter. The water heater...

Have you verified that you have 12 Volts DC to gas valve when it is trying to ignite? If you have the little thermal cut-off ( looks like a small diode ) inside plastic sleeve going to terminal on thermostat, remove it and connect female end on that brown wire directly to thermostat terminal and see if it lights.If it does, get a new thermal cut-off. It's a safety device so don"t go without it. It shuts off gas to valve if there is a flame up.

I have a reliance power vent heater model 8 40 navto . When the water temp called for the heater to work the solenoid started clicking and when it stopped the pilot flame was out and cannot be relit. The...

First suspect is always to clean combustion parts.
I don't have that specific manual, but assume unit has digital gas control valve thermostat.
As a general rule, the gas control thermostat activates the blower and turns on the gas, and controls flow of gas to pilot.

If the ECO is tripped, or there was FV event, or the gas valve thermostat is bad, or the combustion parts and tubes need maintenance and cleaning, then the pilot will not relight.

I have a 50 gallon gas Whirlpool water heater that I installed March of 2005. It's a 9 year warranty. It just started to flame out this morning. I relit, then turned to warm. It started to light up,...

Hi, I work in a plumbing store and that problem you described is related to a piece called thermocoupling, its a coppery thin line that heats up and controls the flow of the gas. If not this then I would check to see if your flue pipe is a bit clogged as the heat is not able to flow up quickly enough. Another culprit can be a problem with the vent pipe on the roof, as a non properly functioning vent will let draft down to the flue pipe. Most likely I think it is the thermocoupling though. Hope this helps!

Water heater pilot keeps going out. Relight and may stay lit for a day and then goes out again. Now won't even light at all. Has an igniter button. Also says to clean intake screen every 6 months. Where is...

the intake screen or as is called flame trap is located on the very bottom of the heater underneath. this is very important that you keep this clean or it will keep going out. this is the only way this heater has to get air to the burning chamber.

Relighting the pilot of any water heater is a pain. The first thing to do is call the water heaters manufacturer for information on your specific make and model. If your water heater is under warranty, they will provide technical advice and free parts.
1. Replace the water heater's thermocouple. Make sure the pilot flame is centered on the shiny end of the thermocouple; it requires a certain amount of heat to produce enough electricity to open the main gas control valve.
2. Replace the main gas valve control.
3. Replace the water heater; I know this not what anyone wants hear.

Pilot lite went out and will not relite

The thermocouple is not functioning. The t/c is the small (sensor) tube that the flame touches and should have a small copper tube (capillary) extending to the gas valve. (IMPORTANT: The capillary tube should not have any kinks or crimped places...Only gentle bends. A crimped tube will require t/c replacement.) The flame will deposit a coating (minerals) that will insulate the t/c and prevent it from working. Clean the sensor with steel wool, fine sand paper (emery board) or scotch pad. Now try to relight the pilot making sure the t/c sensor is contacted by the flame, if not, shut off gas and adjust. Once aligned and contacted by pilot flame, hold for a minute, allowing the t/c to warm up fully and signal the gas valve to operate when knob is turned from pilot to operate.

Pilot light goes out each time the jets stop heating

This is most likely a thermocouple problem. Try replacing the thermocouple. If it still does it then the draft from the fire is pulling so hard that it pulls the flame away from the thermocouple just after the flame goes out. readjust the way the pilot flame hits the thermocouple to keep it on the thermocouple...

Replace the thermocouple.

Thats the flame sensor.

If the gas valve is not sensing flame it will not stay lit.

T-couple's are about 9 bucks.
