Thermostat and on switch do not turn on heater.

The on/off switch and thermostat switch do not open the gas valve to allow the heater to start heating. is there a way to bypass and open the valve manually?

SOURCE: pilot will light but main burner will not light

if burner lights after jumping valve you have something wrong in thermostat loop. disconnect the 2 thermostat wires on gas valve and use multimeter on continuity setting. if all wires ,connectors and components are good,you will get a tone.since you have jumped out each component in thermostat loop with no success ,i would suspect a bad wire or oxidation on a terminal .

Hi


1. Turn off the power to both the pool/spa control system and the heater unit.
2. Remove the front panel door from the front of the heater to access the raceway.
3. Run the wires from the pool/spa control system through the opening, Thermostat is located on the lower right or left hand side of the heater.

SOURCE: FL2 Error Code. Ignitor

FL2 = the flame sensor doesn't detect the presence of the flame so the burner is shut down.
The sensor is a thermocouple that changes its resistance when heated - carbon build up has little to no effect on it but, if present in large quantities on its insulating post, can short the sensor to the ground so clean it with sanding paper. In your case you have a bad connection between the actual sensor and the control board - you will need to inspect it and locate it. If you can't locate it then it's either in the sensor's casing (you will need a new sensor) or in the control board - there is a bad soldering in there and you will have to redo al of them.

How to Change the Gas Valve and Thermostat on a Hot Water Heater


<p>If you are having<b> trouble with the temperatures</b> of your <b>gas hot water heater</b> fluctuating too much, or after <b>changing the thermocouple</b> of your gas <b>hot water heater</b> then you may need to change the complete <b>gas valve and thermostat assembly</b>. Also if you have changed the <b>thermocouple</b> and the pilot still will not stay lit, then the gas valve could be bad or the <b>ECO (Emergency Cutout)</b> may have activated and is open. This is a onetime device and cannot be replaced.<br /> <p><br /> <p>These instructions are for the older style <b>gas valve and thermostat combination</b>. These commonly have a large red knob that adjusts the temperature of the water. Also note that the burner tube nut for <b>natural gas</b> is right hand thread, but if you have <b>LP or propane gas</b> the burner tube nut is left hand thread.<br /> <p><br /> <p>The newer <b>gas valve thermostat combinations</b> that have come out recently are similar, but they have a well in the tank that the sensor slides into. The assembly is held fast with a set screw. With this type of <b>gas valve and thermostat unit </b>the tank does not need to be drained, but most of the rest of the change out is similar.<br /><br />To change a <b>gas hot water heater thermostat</b> you will need to first buy a new gas valve for your <b>hot water heater</b>. The <b>gas valve</b> and the <b>thermostat</b> are integrated into one unit.<br /><br />To <b>replace the thermostat on a gas hot water heater</b> you must follow these procedures....<br /><br />1. Turn off the incoming water and<b> drain the hot water heater</b>.<br /><br />2. Remove the <b>pilot tube</b>, the <b>burner gas tube</b> and the thermocouple from the gas valve. Turn off the <b>gas line</b> and remove from the gas valve.<br /><br />3. Get a <b>pump pliers</b> or a<b> wrench</b> in behind the gas valve and turn the whole assembly CCW to remove it from the tank.<br /><br />4. After applying pipe dope or tape to the new gas valve threads, turn the new gas valve into the tank by turning in a CW direction. Be careful not to damage the small wires to the <b>ECO</b>. They are the little red wires on the back. If you break them the assembly is irreparably damaged.<br /><br />5. Reinstall the gas line, thermocouple, burner tube, and the pilot tube to the gas valve.<br /><br />6. Fill tank with water. Make sure to open a <b>hot water faucet</b> and <b>purge all air from the tank.<br /><br /></b>7. <b>Check for leaks</b> where the gas line hooks up with soapy water.<br /><br />8. Relight pilot light and check operation.<br /><br />9. Set the new temperature setting to a medium setting and then adjust the temperature to your liking from there and adequate time for heating completely<br /> <p>

Water gets to hot even when turned down all the way thus opening pressure release valve


I can get you started but might need more information.
Do you have tank-type electric or gas water heater?
Or indirect heater, or boiler, or tankless, or condensing, or under-counter?

If you have ordinary tank-type electric water heater, the thermostat is probably bad.
Replace thermostat(s)

If you have ordinary tank-type gas water heater, then thermostat can be bad, and thermostat is located on the gas control valve

I have a 1992 bounder mh ,6a6e atwood water heater.I recently replaced the coach batteries and main battery.My circuit board went bad,replaced along with eco and thermostat.My gas valve was rusty and...


First check thermal cut-off that is connected between incoming power wire and thermostat terminal. (located inside little clear plastic sleeve) Easiest way to do that is to remove it from the circuit temporarily. Just pull it off thermostat terminal, pull it apart from other end, and just connect female spade from incoming power wire directly to thermostat terminal. Then see if water heater ignites. If it does, and all works well, get new thermal cut-off. That cut-off is a safety feature in case of flame up at burner, it will shut off gas supply. It is not reset-able, just works once then needs to be replaced.
If that doesn't cure it, take a 12v test light, or a multimeter, and test for power at gas valve, when water heater is trying to ignite, or at ECO terminal where red wire runs from left ECO terminal to gas valve. If power is getting to gas valve, and you don't hear or feel it click, make sure ground connection is sufficient as well. If you have 10.5-13.5 volts to gas valve, and it's not opening and ground is good, then it's faulty and should be replaced. If it is clicking, (opening) but no gas coming through, you may have a plugged orifice on gas valve, provided you have cleaned burner tube of any spider webs or debris previously. If no voltage from red wire, start back tracking with meter or test light to other terminal on ECO, then to terminals on thermostat as well. You'll see how feed wire (short jumper) goes from thermostat, over to ECO. Remember, you will have to hold test light or meter probe at connection and have someone turn on switch to get a reading, which will only appear when it's trying to ignite. Let me know what you find.

We have a gas wall heater product number 4690011 and we do not know how to start it;


Remember if you smell gas, turn unit manual gas valve off and open a near by window, wait until smell is gone then proceed with these directions,turn manual gas valve back on, turn thermostat down.1.) turn combination gas valve knob to the pilot position and press down knob, if unit has a striker button, push striker while holding down knob until pilot lights, keep knob held down in the pilot position for 20 seconds then let up on knob and turn to the on position, turn thermostat up, main burners should light.

Carrier Gas Furnace and Hunter Thermostat not working


Definitely a furnace issue. The gas valve is not opening if you see no flame. I have seen the igniter glow but not send enough voltage to the circuit board to make the gas valve open. If this is the case you should replace the igniter. It is very fragile so please use care when replacing. Check all connections at the circuit board as well as the gas valve. Check your gas supply. Check to see if you get 24 volts AC to the gas valve. If no, replace the circuit board. If yes, replace the gas valve once you confirm that you have gas to it. If you get a pilot flame only, you will need to clean the burners and flame tray that spreads the flame from one burner to the next.

Heater will not fire. Will stay lit when both TH wires are removed. New pilot assembly and gas valve. Thanks.


The TH wires are either end of the THermostat circuit, otherwise know as the safety circuit. Something in that circuit is open and not allowing the gas valve to open and burners ignite. The most common is the pressure switch but it could be any one of the 8 or so switches that must all be closed in order for the heater to fire.

Whirlpool gas dryer- Series MK1159224


Just a quick thought...make sure that your gas shut off valve is ALL the way open.
In answer to the thermostat question, if the thermostat has completely failed, (open circuit) you're correct, there would be no heat at all. The thermostat contains a tiny heater, controlled by the heat select switch, for instance, if you set the switch to "low heat" the thermostat heater will turn on, applying heat to the thermostat, which means when the main heat turns on, the thermostat will cycle off quicker, because although the air temp may be, say...120F, the thermostat is at 160F. So, that being the case, you could possibly have a problem with the temp switch applying voltage to the thermostat heater constantly, and excessively. Or, the thermostat could just be cycling too quickly. This could be tough to pinpoint exactly without taking some voltage readings with the machine running....one way to check the switch is to remove the two small wires from the thermostat, (leave the larger wires on) and see if it heats properly, that would mean the switch is bad. Please remember to unplug and verify that there is no voltage with a meter before messing with any wires. Hope this helps narrow it down....
