Hot water heater thermostat

I can't get the pilot to light on the Honeywell thermostat. The gas is on but I don't smell anything when I push in the knob in the Pilot position.

The pilot light on the water heater went out and the red light is blinking four times on the thermostat (Honeywell WV8860B1317). How do I get this to stop so that the pilot light can be relit?


The flashing light 4 times indicates high water temperature has activated the over heat sensor, and that the only remedy is to replace the gas control valve/thermostat.

How can we ignite the pilot switch


The directions are on the inside cover of the water heater as well as on the paperwork you received with the unit.
If you have none of these, get the make and model number of the unit and look it up on the internet.
General directions to light a gas appliance:
1.Turn the switch to, "Off"
2.Remove the 2 panels at the base of the unit.
3 Identify the pilot device.
4.Get a long lighter or match on a stick that reaches the pilot.
5.Turn the gas knob to the, "Pilot" position
6.Light the match and put it next to the pilot while pressing down the knob
7. Keep the knob pressed for about 45 seconds after the pilot lights
8. Let go of the knob so it's in the, "up" position
9. Turn the knob to the, "On" position
-the water heater should fire up in under a minute.
10. Put the metal panels back into position.

My Bradford White Defender M-I-30T6FBN doesn't show igniter button on instructions


1) Copy following links to identify gas control valve and read ignition procedure, and access service manual for your product:

2) Honeywell gas control used on recent Bradford White gas water heaters has red knob that rotates to pilot. Press and hold red knob. Then push red igniter button until status light changes.

Can't light pilot light on hot water service. Gas to property is connected as the gas stove works.


There should be a trouble shoot guide on the hot water tank. I have had to do this many times. You just need to read the trouble shooting guide & be very careful. I hope this works for you.

Honeywell WV8840B1109 temp control valve on water heater. Status light @ 4 blinks between 3 seconds indicating "high temperature shutdown" even though lighting pilot with water cold. .


II have exactly the same problem: Honeywell WV8840B1109 temp
control valve on water heater. Pilot is on, but the burner won't
no matter how high I turn the temperature knob. Status light blink
4, which by the controller is "high temperature shutdown" and has
nothing to do with the problem. The real problem is that the
computer chip in the controller has gone bad. Problem is solved by
changing a new gas control valve/thermostat. The old Honeywell
control valve uses pure mechanical stuff and was very reliable,
almost never has a problem. I don't understand why they switch to
this new electrical one which use the tiny voltage generated by
the thermopile to run, easy to break, because of the electric
chips, and is more expensive. The only reason I can think of is
that they want to get more money from our pocket.

You need to inspect and clean the air intake located on bottom of unit. Get more fresh air to the water heater and see if problem continues.

Instructions for lighting the unit are located on front of water heater.
Other possible causes include: bad gas control valve, dirty combustion parts, reverse draft down the stack (caused by wind and opening door inside closed utility room), low gas pressure, air in gas line, etc.

Propane gas is heavier than air. So if you have a gas leak, then smell close to floor. Leave house immediately if you smell gas. Install a gas detector close to floor level near gas appliances.
Most water heaters today are extremely safe, because we experimented on prior generations of people, who then passed along their experience.

Atwood G6A manual water heater had gas flare up around the control knob when lighting the pilot. Unit is about 9 years old so repair or replace? works OK & no gas smell.


The gas control is leaking gas around the knob?
The gas control needs to be replaced before causing explosion and/or fire.
Gas control has identifying marks on side.

Reliance 606 natural gas water heater - model #640YORT - water does not stay hot. pilot has to be clicked to heat and then u can use hot water til tank empty and it will not continue to heat water.


If I understand correctly, the pilot light is not staying lit.
You light the pilot and water in the tank reaches temperature.
Once hot water is gone, then pilot light has to be lit again.

Gas pressure is good, and gas is flowing.
Thermostat is working at high end because it cuts off heating.
Vent is working because tank heats up.
Air intake is working.

Gas control thermostat might not be reading low temperature. Replace gas control valve.
Pilot tube might be dirty. Clean burner parts and combustion chamber, and air intake, and vent.
Backdraft might be blowing out pilot. Check for constant updraft by running water heater 5 minutes, and then light match under vent hood and see if smoke goes up.
Very hot air can put out pilot, especially when water heater located in attic. Add ventilation.
Improper vent might have water dripping back down into combustion chamber and putting out pilot light and rusting out the parts. Inspect for rusted parts and water.
