SOURCE: how do i reset safty switch on ge gas water heater

If your water heater has the flame lock system, there has been a recall and the whole burner assembly will have to be replaced. I recommend you call a plumber.

How to change a envirotemp gas water heater into a.electric water heater


Dear Buffie,
You cannot change a gas water heater into an electric water heater, nor can you change them the other way around.
They are manufactured differently.
If, however, you are getting rid of the gas one and want to know how to hook up a electric water heater in it's place, please ask the question that way.
God bless your efforts.

Propane water heater high limit switch keeps kicking out


1) What brand and model water heater?
Copy following link for troubleshoot by type of gas control valve.

2) Clean air intake screen using compressed air or feather duster.
With AO Smith, craftmaster, state, reliance, american, kenmore, whirlpool, the air intake is located on bottom of heater. Rheem, richmond, ruud, GE, Bradford white, the air intake screen is located under combustion parts.
Water heaters today require plenty of fresh air. If air intake gets clogged with dust, then combustion byproduct moves up pipe too slowly for amount of fuel being burned, and this overheats combustion chamber.

Certain Rheem water gas water heater models feature electronic controls with a flammable vapor sensor installed on the bottom portion of the water heater unit. This sensor is designed to shut off your water heater system to prevent fires in case flammable vapors are present within the area. If your flammable vapor sensor caused your water heater to shut down, check the area immediately for leaking gas or other flammable products. Common household chemicals such as bleach can also trip the safety system as well as unsuccessful burner ignition attempts.


White Rodgers Intelli-Vent PowerVent Control Equipped Models
  1. Step 1 Turn the water heater's blower switch off and disconnect the power cord for the water heater (refer to your particular model's operation guide for the exact location of the blower switch). Disconnect the Molex connector attached to the bottom of the control pad (the left most connector with five pins).
  2. Step 2 Turn on your multi-meter and set it to read resistance or "ohms". Connect one of the multi-meter's probes to the number two pin and the other probe to the number three pin of the Molex connector (middle black wires). If the reading on your multi-meter reads below 9k or above 45k ohms, the flammable vapor sensor is faulty and in need of replacement; you cannot reset the system until this issue is resolved.
  3. Step 3 Reconnect the Molex connector to the bottom of the control pad, reconnect the water heater's power if and turn the blower switch to the "ON" position. Press both the left and right buttons on the control pad at the same time. Wait for the green light on the control pad to blink and press the following buttons in sequence: Left, Right, Left, Left, Right, Left, Right, Right (you will need to perform these actions within 30 seconds of reconnecting the power cord to the water heater in order to be successful

Light flashing - lockout condition - ECO failure


The ECO is designed to shut off the water heater in case of the water heater overheating. This is to prevent the water heater from exploding. I assume that you have a newer style residental water heater or a commerical boiler. The ECO is a fuseable link that is built into the control and located at the thermostat probe. If the water heater overheats then this link will melt cutting the circuit on the millivolt system(residential) or 24volt system(commercial boiler). If you look under the water heater control(where the temp adjustment is) there are usuall two wires that go from the control to the water heater. These are the ECO wires. Verify the wires have not been cut or damaged. If these wires are cut or damaged then the ECO circuit will be incomplete and you will get the ECO lockout failure. Also make sure that the flame lock-out switch is not tripped. It will be located at the burner compartment cover and have two wires going to it. Most have a little button in the center. These are to sense high heat and one might have tripped closing the circuit. You can push this little button to re-set the switch. If you feel a little "click" then the switch was probably tripped. If it does not have any button then it might be "self resetting". To test that switch use a continuity tester and the circuit should be closed. If these switches are working then the fusable link for the ECO is probably bad from the water heater temp getting too high or was defective and failed. This will require you to remove the water heater control valve and replace the fusable link. If you do not have experience with this I suggest you call a licensed plumber to make the repairs. If this repair is improperly done it could void the warranty on the water heater and/or cause property/personal damage or injury. There is a possiblilty that your water heater thermostat had failed causing the ECO to trip. If that is the case then the ECO safety did it's job.

Burners will not disengage after shutting off Hot Water.


Ok the way this system works is from a pressure and flow switch. The pressure switch picks up the slight drop in pressure when the hot side water is turned on then turns on the burner. The flow switch measures the amount of water flowing and adjusts the size of the burner to the amount of water flow. So a couple different things might be happening. The flow switch might be sticking causing the water heater to throttle down the burner but not off when the water flow is off. Or the gas control valve might be by-passing gas when off causing the burner to stay on even when the demand is off. Run the hot water on high demand then turn the water off. If the burner is still on try banging on the water heater with your hand and see if the burner shuts off completely. If it does the gas control valve might be by-passing. You would also need to check and see if the pressure/flow switch is giving any voltage signal changes when the water flow is off. These tankless water heaters are more comlplicated to work on than a standard water heater and you may need a professional's help...good luck

AquaStar 125B NG continues heating water when no demand


I found the manufactures website and read this specific tech bulletin. I will be replacing or repairing my water value soon.

http://www.boschhotwater.com/Portals/7/TechBulletins/TWH-G1-25_Water_valve_rebuild_B.pdf

The bulletin said the following:
If the burners fail to go off immediately when the
water is turned off, usually due to mineralization in
the water valve on older heaters. To test for this
possiblilty, run hot water at a faucet, then shut off
the cold inlet supply and observe if the burners go
off immediately. If they do not the Aquastar will
overheat and shut down on safety depending on
the delay.
