I would contact Whirlpool directly first, a few years ago they had a model that had bad thermocouplers and burner assemblys, especially the one's sold at Lowe's. I worked for an apartment complex that used these and had some go out a month after install.

If there is a cover on the front with a little window you cant fix unit. you must replace the heater.if ont there is a small line that goes to the burner tray.you can replace thermocoupler without takeing the tray out,it is a skilled task.you may need a plumber to come to fix if you can't.

A thermocoupling isn't hard to replace and they are about $6 at Lowes. Just put it back the way you took it off.

Piloit light on606 gas water wont satay lit


If pilot light has gas, then ECO is not tripped so water heater has not experienced overheating event.
Remaining suspects include bad thermocouple, bad air quality, not enough air, bad vent, water dripping down vent, backdraft down vent, hot attic with bad ventilation, low gas pressure, air in gas line, dirt water or debris clogging gas control thermostat, bad gas control thermostat, tripped FVIR, dirty pilot orifice, dirty combustion parts, damaged combustion parts from exposure to trace chemicals like bleach and wax.
Suspects include one or more from list above.

Start with thermocouple.

Richmond 3360 gas water heater pilot won't stay on


Open following links for pilot and troubleshooting resources:
Problem could be bad thermocouple, thermocouple not sitting in pilot flame, pilot orifice needs to be cleaned, water heater needs more air, dirty air intake, hot attic environment, backdraft blowing out pilot, or bad gas control valve.
If you get flame, then ECO is not tripped.

Suspects include bad thermocouple, thermocouple slipped down and not in pilot flame, dirty combustion parts and pilot tube, dirty air intake, backdraft caused by other vent fans pulling air down water heater vent, water dripping down vent because of poor venting, air in gas line, low gas pressure, bad gas control valve, hot attic environment, tight house not allowing enough air:

Hot water heater pilot is off. It's not gas,


You have tank-type gas water heater:
Open following link to watch thermocouple replacement.
Make sure new thermocouple sits into pilot flame. Instructions for relighting water heater are usually printed on side of tank.
http://www.youtube.com/watch?v=v0aBPsNg6vo

Gas water heaters need working thermocouple, adequate incoming fresh combustion air with no trace amounts of chemical, open vent to outside that drafts poison combustion product upward, clean burner tubes and combustion parts, correct gas pressure with no air in line, working gas control valve thermostat, no lockout condition such as tripped ECO caused by runaway heating and dirty combustion parts, and no lockout condition such as exposure to flammable vapors.

My reliance sta-kleen 502 gas water heaters' pilot will not lihgt. can some one give me an idea what to do.


Reliance is Rheem
Replace thermocouple is best start point.
Example Whirlpool manual shows general replacement steps on page 22:
Buy thermocouple at hardware or home center. measure length before going to store.
http://waterheatertimer.org/pdf/Whirlpool-6510397.pdf

Utube videos show how to replace thermocouple

Many things can affect pilot:
Low gas pressure, Water or air or debris in the gas control valve, High-heat event causing ECO to trip requiring new gas control valve, burner and tubes needing clean-out, FV sensor tripped, loose or bad thermocouple.
Manual above shows general steps for doing some of these things, but service technician is probably best choice if thermocouple does not fix problem.

Gas water heaters require periodic maintenance.
If repairs cost more than $330, then buy new gas water heater and install yourself.
Use the old one for a solar collector.

Pilot hard to lite when lites stays on about 15 minutes goes out this is on reliance gas hot water heater 101


The thermocouple has gone bad or in this case is going bad to the point that it is useless.

The thermocouple is the pilot's, well, co-pilot! It is the electronic device that senses if the pilot flame is hot enough to ignite natural gas or propane fuel to the burner. If the thermocouple thinks it's safe, then it keeps open the main gas valve located in the pilot assembly. If the thermocouple does not sense enough heat from the pilot flame (such as when the pilot is out), then the thermocouple shuts off the gas valve to the burners.
How the Thermocouple Works
So what is this thing and how does it work? Well the thermocouple (technically called a thermocouple junction) is a device that contains two metal wires welded at the ends and placed inside a protective metal case. The thermocouple sensor is found at the business end of the pilot flame and is designed to be placed in the hottest part of the flame. The other end is connected to the pilot valve body. As the thermocouple heats up, it produces a small amount of electricity and when it gets hot enough from the pilot, send a signal to open the gas valve by using a solenoid operated by a 24 volt transformer. The thermocouple calls the shots, and by converting heat to an electrical signal, it allows the gas valve to open or close. Once the gas valve is open, gas is then constantly supplied to the pilot and as required for the gas burners (as called for by the thermostat). If the pilot goes out, then the thermocouple gets cold and produces no electric signal to open the gas valve's solenoid and the gas valve shuts off the gas supply to the pilot and burners. Neat huh?
