Question about Water Heaters

Open Question

I have a ruud pacemaker water heater and the burner fails to remain lit. I have cleaned all debris from the inside, replaced the glass vial safety cutoff, the entire pilot assembley including the thermocoupler and the thermostat/gas valve regulator. It looks to me that when the gas is turned to the on position, the flame is starved for air. When i turn the gas to only a fraction of full, I get a respectable flame, but within minutes, the "booster?" flame from underneath kicks on and will shortley thereafter turn off entirely. any advice would be appreciated. The only part left to replace is the entire burner I guess. The Ruud warrenty dept is no help in diagnostics, but they do send me parts for free

SOURCE: After a few minutes of burner heating the water, gas shuts off.

A couple of things to check:

If possible, remove the pilot gas assembly and clean the gas jet and thermocouple - they can get carboned up and stop working properly. Make sure the pilot flame and deflector is aimed properly and making the thermocouple glow red hot. If the problem persists, you may want to replace the thermocouple and also check the propane regulator.

SOURCE: Natural gas hot water heater not stying lit

Probably a bad solenoid in the gas valve. Higher voltage of a new thermocouple keeps it open longer but it still fails over a period of time. Look into a new gas valve for the water heater.

2) If this is Rheem-Richmond-Ruud, then you need new TRD glass vial.
You may also need new gas control valve, EV sensor, and other parts.

3) Might be cheaper to buy 40 gallon gas water heater at Lowes for $385, set 3-legged heater on bricks for ez access to arrestor screen, avoid dusty locations, provide more fresh air to unit, and perform required maintenance such as inspecting/cleaning air intake screen with compressed air.

How to take off the thermal couple off a ge sg40t12txk


1) Copy following links:
http://waterheatertimer.org/How-to-replace-thermocouple.html
http://waterheatertimer.org/How-to-repair-Rheem-TRD.html

2) GE is made by Rheem, so air intake screen is located below the combustion burner, as is the TRD (thermal reset device).

3) Modern gas water heaters, the FVIR, or FV system will trip when air intake gets clogged with dust.
This will slow venting of hot combustion gasses, except burner is still burning same amount of fuel. Overheating occurs, and that trips FV system.
Other brands require cleaning air intake screen and possible replacement of gas control valve, or FV sensor, etc. Each model is different.
Rheem_GE overheating will trip TRD, and glass vial breaks, causing air intake to close. Glass vial must be replaced, and possibly the gas control valve replaced.

Put in gas valve, a few days later sensor set lock out due to flamible sensor setting off. what are the codes to unlock system?


Air intake is probably clogged, so combustion air flow slowed and caused overheating inside combustion chamber.
This tripped FV system and broke TRD, which is a small glass vial located under burner. The spring-activated air baffle snapped closed and shut off air supply, and also tripped FV lockout of gas control.
Remove burner, replace glass vial ordered from Richmond, and clean air intake.

If you have Intellivent gas control, then it can be reset.

Rheem Intelli-vent intermittently goes in lockout mode


Rheem does not post service manuals.
However AO Smith has posted relevant service manual:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent

Have you cleaned the air intake located under combustion chamber, and inspected for broken glass vial?
Rheem FVIR system uses glass vial that breaks if combustion air is slowed, and resulting combustion causes slow-moving venting of hot gasses, causing overheating that breaks glass vial.

Check gas pressure.

Rheem water heater flashes seven times ,it is in lock out mode


You have Honeywell electronic gas control valve, and error code is 7 flashes.
Probably you have power vent model.
One manual from different company says: "Reset gas control using on-off button on front of control, replace flammable vapor sensor, replace gas control thermostat.
But with Rheem you also need specific steps: Remove gas burner and look for broken glass vial, and then blow out arrestor screen air intake using compressed air, clean burner parts, check for unobstructed venting, you will need new glass vial from Rheem depending on year and model number of water heater that appears on label on side of unit, or they may not have a repair kit for that model, and you might need a new gas control valve depending on model and how extensive problem was
You have Rheem water heater.http://waterheatertimer.org/How-to-repair-Rheem-FVIR.html

Have to keep lighting water heater


Clean air intake. Change thermocouple.
American Standard appears to be Bradford White or Rheem product from the one image that appears on the AS site.
Air intake located on side of unit funnels air to arrestor screen located under the combustion burner.
Remove burner and blow out screen with compressed air.
If this is Rheem product, then also inspect for broken glass vial that indicates high-temperature FV event, which might also require other parts to be replaced.

Where is the combustion shutoff system on a Rheem 30 gal moble home hot water heater


Disproportionate number of water heater problems are Rheem-related, yet Rheem is just 1 of 3 major water heater manufacturers.

If you have Rheem tank-type gas water heater, and the combustion shut off has tripped the FV system, then there is a broken glass vial located under the burner.
Rheem does not post service manuals, and they may or may not send the glass vial for replacement. Depending on model which appears on label on side of tank. Year of manufacture are 3rd and 4th digits in serial number.
And they may want you to contact a qualified service technician (plumber)
You will have to replace glass vial, and clean the arrestor screen and clean the combustion parts, check gas pressure, and check venting.
Other companies post service manuals and do not rely on the glass vial.

Water heat will not stay lite. will light but goes out when you turn the knob from pilot to on


Water heater brand, model number, type, location and approximate age are not known.
It is possible that water heater has tripped the FVIR system.
Water heaters manufactured last several years will shut down if exposed to flammable vapors, or high heat inside combustion chamber caused by inadequate air supply or clogged air intake, or bad venting.
Solutions range from replacing water heater, to cleaning air intake, to replacing-resetting TCO, replacing TRD glass vial, replacing gas control valve, installing louvers so more air gets to water heater, removing water heater from dusty environment, etc.
Other cause can be bad gas control valve, and possibly bad TCO, or tripped ECO requiring reset or replacement of gas control depending on specific brand and model number.
Review you product manual, look for identifying information on label on side of water heater.
