Question about Williams 3003622 Ceramic Wall Mounted Panel Heater

1 Answer

Heater will not run more than 1 cycle.

You can light the heater and leave it on pilot as long as you want and it will never go out, once you turn it on it will run a complete cycle then shut off normally. The next time it tries to come on it goes out immediately. It does this faithfully every time!!!!!!!!!!!!!!! Help.

Check your thermocouple. You should never leave it on pilot to run. The Thermocouple detects flame and it doesnt seem like it is detecing the flame. You can go to a local appliace shop and pick up your new thermocouple

Kozy world propane wall heater pilot will not light

This can be caused by several things:

1. The inline gas valve running to the the heater is OFF. Turn the valve ON.

2. The gas control knob on the heater is not exactly in the PILOT position. Unless the knob bottoms
out and you feel strong pressure (other than spring pressure) pushing back at you. It's not exactly
in the PILOT Position. Once the pilot lights, hold the control knob in for 30 seconds to 60 seconds
to allow the Thermocouple to full heat.

3. The pilot is dirty and needs to be cleaned, as do the burners.*

4. The LP Gas Tank is empty or to low to maintain te proper gas pressure.

* Here is a link to a demonstration on how to properly clean the pilot & burners.

I hope this helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

Hayward H 300 series pool heater for an inground pool. Pilot light is lit. Filter is clean. If I jump the terminals the heater will go on. If not the heater will not start.

I have an H300 Millivolt Hayward heater. It will start and run for about 1 minute then shuts off along with the pilot going out. I've tried cleaning all the terminals and running all new wiring but same result. I've also jumped out the TH to TH terminals leaving the jumper in place and it still shuts down after 1 minute. Any idea what that could be ?

Rheem NatGas hot water heater model 41V50, basement flooded pilot went our how do I relight?

At the controls there should be a knob that says " Pilot"... "ON" Turn the knob to pilot and hold it down while lighting the pilot lite. Keep holding it down until it gets warm enough that when you leave it up the pilot stays on. Once the pilot lite stays on on it's own turn it to on.

Procom qd 250 keeps shutting off

If the pilot light keeps going out, the pilot and Oxygen Depletion Sensor (ODS) need cleaning.

What you'll need: A Phillips head screw driver. A can of compressed air with a straw nozzle )like you clean your computer with).

Be sure has is turned off to the heater. Remove the front cover of the heater cabinet by using the phillips scew driver to remove 4 to 6 screws around the outer edge of the cabinet. Once that's complete you will have access to all the components of the heater. If you see a lot of dust and lint inside the cabinet, use a vacuum cleaner that has a hose and brush attachment, to carefully vacuum all of the interior. Once that's completed look for the pilot assembly. Once you have located it, use the canned compressed air with the straw nozzle attached, to blow out the pilot tip. Just one quick shot of air should do it. Now, move your attention about 2/3rds of the way down the pilot from the flame tip and you will see a small hole in the side of the pilot. Using the canned compressed air and straw nozzle, put the tip of the straw just barely into the hole and hive it a quick, firm shot of air. You will probably see debris blowout the other side.

With the front of the cabinet still removed, turn the gas back on and try to light the heater, just as you always have. It may not light on the first try, because their may be some air in the gas line. Once the pilot lights, continue to hold the Control Knob in for 1 minute. Then ease off the Control Knob. If the pilot stays lit, wait one minute and turn the Control Knob to ON. The burner(s) should light and function as they should. Turn the Control Knob back to Pilot and look at the pilot flame. Is it curling up and away from the Thermocouple? If it's not, your problem is solved. It is curling up and away from the Thermocouple, Turn the Pilot OFF and clean the pilot again with the compressed canned air.

Reassemble the heater cabinet and pat yourself on the back. You just completed what's called "Annual Maintenance". Which should be done every year, before you fire up the heater for the Fall and Winter.

Hope that this helped in solving your problem. Please be kind enough to let me know.

Do not know how to start pilot light

There should be instructions on the inside of the heater access door. Make sure you are comfortable working with gas heaters. Make sure the shutoff valve supplying gas to the heater is on. Turn the gas valve to "pilot", press and hold it while attempting to light the pilot. Once the pilot is lit, continue holding the gas valve knob down for about 30 seconds. The pilot should stay lit once you release the knob. If the pilot stay lit, turn the gas valve to "on". Replace the heater access door and make sure you have proper water flow and attempt to light the heater. If it will not light, or the pilot will not stay on, you will probably have to replace the pilot generator. It provides voltage to run the heater and after time it wears out and produces less and less voltage. A millivolt heater runs on less than one volt so any power loss can be a problem. If you are able, test the pilot generator with a multimeter to see if you are getting at least 500mv when the pilot is on. If not, you should replace the pilot generator or even the entire pilot assembly. Hope this helps...

Lighting a glo warm heater

Is this a new heater or have you had it awhile? If new, yuo may have air in the line that will need to be bled out. The heater has a gas valve with a pilot setting on it. Make sure the gas is turned on. Turn the knob to the pilot setting and depress the handle. Holding it down and at the same time, press down on the red button that sparks. You may have to repeat this a few times. Once the pilot lights, continue to hold down on the pilot knob for about 30 seconds. When uou release the knob, the flame should stay o. If it does not, replace the thermocouple. Once the pilot flame is steady, turn the gas valve knob to on.
