Question about Cozy (W352E) Heater

1 Answer

Pilot lights fine, furnace fires up, when it turns off the pilot goes out

I have a cozy wall furnace - probably 6-7 yrs old. The pilot lights fine and stays lit for many days, but every 3-4 days it will go out. Usually it is when the furnace has just kicked off as it shuts off, the pilot goes out as well. I have replaced the thermocouple - no fix. Any ideas?

    I have the same problem, but with a furnace instead of a wall heater. The pilot lights the burner and the blower starts, but when the burner shuts off it snuffs out the pilot. The pilot never goes out at any other time - only when the burner shuts off.

    Is the pilot a good flame say at least 3/4 to 1 inch long?

Need to have at least 3 feet of vent out of the roof, if it is to low the coll air will cold soak down to the pilot and shut it down.

I have a Cozy W355D wall furnace. It's difficult to turn on. Replaced the thermostat, that helped some, but still have to turn it off, wait a few minutes, and turn it back on. Often still won't light.


So are you saying the pilot stays lit, but the main burner won't always fire. If this is a millivolt system you could have a weak pilot flame, not getting the pilot generator hot enough or you could have a weak pilot generator. If you are handy you can try cleaning the pilot. It may be better for a qualified service tech.

I AM WORKING ON A COZY W501E WALL FURNACE AND CANT GET THE PILOT TO STAY LIT. i HAVE CHANGED THE GAS VALVE, THERMOCOUPLE,AND THE SENSOR FOR THE HIGH LIMIT. THE PILOT WONT STAY LIT.


Pretty much the only thing that will do that is the thermocouple not generating enough voltage for the valve to say it's OK.
Usually you need to hold the button for pilot lighting for 60 seconds. You can use a meter to check that it's generating enough power. The thermocouple has to be in the pilot flame properly.

Cozy gas wall heater won't ignite, pilot light is on


There are two types of igniters, spark-type or glow heater. The glow heaters wear out and crack or break and the spark-type spark gap gets fouled or dirty. Both could have electronics problems that drive the glow heater or spark systems. The Filtrete thermostat is not the issue. While rapping the unit makes the glow igniter come back together to glow again.

Cozy wall furnace (propane) does not respond to thermostat. The pilot is lit. Furnace is 3 yrs. old and rarely works. The wire to thermostat is 20 feet.


Try jumping the two thermostat wires together to see if the heater starts. If so, replace your thermostat. If not, jump the two terminals where the thermosta twires attach to the furnace. If it starts, you have a bad thermostat wire or connection.
