Question about Heating & Cooling

1 Answer

I have a Cozy one-sided gas wall heater. It is no longer lighting the burners when the wall thermostat reaches the temperature set point. The thermostat will "click" on, but the burners won't ignite in the heater. This has been an intermittent problem, but is growing steadily more frequent by the day. Sometimes when the burners won't ignite, I'll bang on the heater and then they ignite. But even that "temporary fix" is becoming less effective. What part on the wall heater needs to be replaced or serviced so that the burners light when the wall thermostat sends out its signal? A new wall thermostat was installed about a month ago because the same problem was happening with it, so I know it's not the thermostat.

Can you remove the front cover to the wall unit? Look for the wiring and follow it till you see a round about the size of a fifty cent piece. Should have 3 of them. One of them is not closing and allowing the signal to go through. So turn up the t-stat to call for heat take each one of the limit switches and by pass them one by one till you find the one that is bad. Depending on where you hit the cover is where I would look first. The limit's are rated by temperature so replace with correct size. You should be able to see the temp. on the limit something like 180 is what you are looking for. Also make sure the wires are in good shape where they connect to the switches. Might have a loose connection. ken

Fan on gas wall heater shuts off and on every 3 minutes, but the flame is on the entire time.


It always helps to add the model number of the item you want help on. However if it's like the newer units, the fan operates whenever the heater wall has reached a high enough temperature and shuts off when the heater cools off. It is not wired into your thermostat or electrically wired to the heater. It does that with a temperature driven fan switch in a little junction box mounted to the heater. Normally when that box gets hot because the heater is on the fan comes on, when it cools off the fan goes off. The junction box will have an ac cord coming out of it. If this fan switch junction box is not properly mounted it could be getting cooled off when the fan starts and then shuts itself off. After it heats up again it starts the fan. The other possibility is the temperature based fan switch is failing and needs replacement. See link.

in front of the burner it is next to a copper tube(black if it has been burned)! it angles a little towards the copper tube! u turn the knob on gas valve to pilot then hold down and light hold for one minute then turn it to the on position (u might have to push down slightly as u turn the knob) make sure u have thermostat to the lowest setting before u light the pilot so it won't turn on while u have your face too close to the heater then turn your thermostat up to desired temperature when it is on the the on position! Good Luck!!

Noisy pilot light Vulcan Quasar 40


Simply clean out the jet tube with a fine wire, the sound you hear is the gas blowing by the irregular edges, and swirling and not mixing and producing sound waves, (Bit like a flute) So, you need to clean the tube right out, and smooth off the end again, & sorta "Countersink", Flame the end too, at the end.use a very fine needle file, and make it look like new, that will sort your problem out. Then adjust so you have a good gas flow. Also check out it isn't blocked too.

My Cozy Heater sized and installed by professional will not heat


I'm assuming your heater is the little Cozy direct vent wall furnace, your room calculations are correct, and at 57 degrees your main burner is constantly on. If so, it sounds as if you have too low a flame which can be caused by a main burner jet with an undersized orifice (like a propane one that got in the wrong assembly line) or obstructed by dirt, inadequate gas pressure, or a main gas valve that is not fully opening.

Open the pilot light inspection door and look at the main burner flame height. If it is less than 2 inches or so, check out the three possibilities above. If the flame is very yellow and wandering around lazily, check the air intake on your vent cap for obstruction.

Cozy dual sided wall heater


There isn't much to these things, its either the pilot generator or the gas valve. Or maybe both, try the first, then the second.
