Question about Montgomery Ward (223600UP) Heater

Ward Heater Company M0021

I have a floor heater, that is pretty old, maybe 50 years or so. I can't read the Model Number. The pilot stay lit, but when I adjust the thermostat for heat, nothing happens. The burner doesn't click on. It did work the last time it was cold, about six months ago. The gas company says it may be the blower. Most of the unit is under the house, it is a pretty deep unit.

Thanks for your help.

    I appreciate your comments. I haven't had the chance to try your solution (crawling under the house wasn't my first choice either). I opted to buy an oil heater, temporarily. Thank you for your help.

These old units have a simple gas valve and a separate regulator. Your best bet may be to replace the gas valve to something more modern. Trouble shooting this most likely be a waste of time, as parts probably aren't available, other than the thermostat. by-pass it, (connect the 2 wires together) and see if it comes on. The blower shouldn't stop the burner to come on. Sounds like the gas company doesn't want to crawl under there to light it.

Rheem 22V50F1 pilot won't stay lit. Changed thermo couple & it lit, ran then went out. Let it sit overnight & it lit, ran then went out. What next? p.s. The unit is 5 years old. Thanks


If pilot lights and flame is robust and clear blue, and pilot goes out later, then some suspects can be excluded: air in gas line, low gas pressure, thermocouple is overtightened (finger-tight + 1/4 turn), thermocouple not positioned correctly in the flame, dirty pilot tube.
If flame is yellowish and small: then clean pilot tube and combustion parts.

Remaining suspects can include: air in gas line, low gas pressure, bad gas control valve, tight house so household vent fans pull air down water heater vent that blows out pilot, hot attic with inadequate ventilation, water dripping down vent.

I have a Rheem 50 gal. natural gas water heater mod#21V50-6A followed all instruction and can't get pilot light to stay lit.


The most common reason a pilot light will not stay lit is a bad thermocouple. How old is the water heater? If the pilot light will light, but then go out when you release the safety button, that is a sure sign the thermocouple is bad. You can buy a replacement thermocouple at your local home improvement store. There is a small chance that the control valve has gone bad, but that is highly unlikely.

Coleman Gravity Floor Furnace need millivolt gas valve & pilot ki


Go to www.grainger.com and look for a "power pile generator" this is a millivolt thermocouple that may be just what you need to make your heater work again

Water heater will not stay lit even after replacing thermal coupl


The pilot must encompass the thermocouple "bulb" in order for the thermocouple to generate enough current to keep the pilot valve on. You must also hold the red button down for a long enough period to get the thermocouple hot. If the pilot is not large enough, it could be due to a clog in the pilot orifice at the pilot itself. Sometimes a couple of passes over the end of it with fine steel wool is all it takes to clear it.

Hope this helps. Feel free to share what you found. Thanks.

Floor furnace


That is the control for the main gas valve. These old ones have a gas valve separate from the pilot. Also the regulator is separate unit. You have to turn these controls with a long rod, right?
