Question about Cozy (W352E) Heater

2 Answers

The heater will not ignite properly and the heater will not shut off

---The heater will not ignite properly

The thermostat is left at 60 degrees to keep the heater off. When the thermostat is set up to 75, the heater goes on for two seconds and shuts off.

If the heater is left alone, it continues to go on for two seconds and shuts off, over and over, or it may not go on at all. This lasts for 20mins to an hour. Eventually, the heater goes on and stays on.

If the heater door is slapped a few times, the heater will go on and stay on.

--The heater will not shut off
Once the heater gets going, it won't shut off. The thermostat to be turned back down below 70 in order for the burner to shut off.

Note:
There heater's multi-volt generator was replaced last February 2007, and the heater appeared to work OK for awhile: it went on and stayed on when the thermostat was set above room temperature. However, the ignition problem soon returned (the heater had to be banged for the burned to stay lit), and it appears to be more pronounced this fall

    how to test pilot generator

  • apatheticopo Jan 28, 2009

    one night our cozy wall furnace (w355f) stopped working. Being a guy, I tapped on the gas valve (not the shut off valve) and the heater started working again. Problem repeated so I replaced the gas valve. worked fine for a while (days) then problem repeated. Replaced the pilot generator (even though no problem with pilot staying lit). Same thing -- Worked for a while tapping the valve got it working then it stopped again. But then the burner started cutting out. When it came on, it would stay on for 3-4 seconds then off. Not being too many more parts to replace, I replaced the thermostat. Initially it would cycle fine as the t'stat was adjusted. Now, we're back to the intermittant working and the burner cutting out......HELP!!!!! I'm thinking the only piece left to replace is the burner assembly otherwise one of the new parts are bad

Judging by your pics (helpful, by the way) you have a high limit wired into your thermostat wire. Try disconnecting that wire nut connection in front of your valve and hooking the thermostat straight to the top and bottom posts on the valve (eliminating the high limit). If it runs fine, either the connection was poor or your high limit wire is pinched.

If you have a programable t-stat, try changing the battery. most of the time that is the problem for that condition.

How to reset the thermostat to shut off after 2 degrees/CT87B-4008?


on these thermostats remove the outer ring cover and in the lower right side you will see a slide adjustment. move it i believe left for closer cycles and right for longer cycles. it should be 2* on either side of set point. remember that the fan is not furnace shut off.and turning back and forth will not tell you anything. just set it and see how it works then change it again if you need to

Pilot and burner light then gas shut off model 7900


How many degrees before it reaches desired temp, does it shut off? A thermostat is designed to shut the furnace off a couple/ few degrees before it reaches set temp. It has what is called a heat anticipater, which shuts the burner down, and lets the blower use the remaining heat from the heat exchanger to bring it up to desired temp making it more efficient. If it is more than a few degrees, replace the thermostat. You can jump out the red and white wires to confirm the faulty thermostat. If by doing this, the furnace never shuts down, until you separate the red and white wires. That confirms a faulty thermostat. Hope this helps someone.

Some thermostats have a default lower limit such as 60 degrees to prevent complete loss of heating. The lower limit is not set by the user.

Freezer is cold, but cold air is not circulating in refrigerator


Check freezer fan is working.If ice formed over freezer fan by working. It's a common problem due to irregular defrosting. Keep freezer setting temp at 5 degree. And check defrost timer, thermostat,heater are working properly.
Turn timer with small tip screw driver to shut off fridge. If not shut off, replace timer. Turn counter clockwise defrost thermostat. If fridge not shuts off replace defrost thermostat.Check heater by join the 2 wires in the defrost thermostat. And after 1 minute, unplug power and keep your arm on heater. If it's warm heater is o.k. Otherwise, replace heater.
Once heater starts work at regular interval controlled by thermostat and timer, defrost will be good and effective cooling will also be in fridge compartment.

The heater will not ignite properly


How old is the thermostat? Also there a limit switches at different points on that unit. If you have a volt ohm meter find the round disc like safety's and ohm them out. Take the wires off the disc before testing them. You should have a continuity should be closed they only open if unit gets too hot. Say something like 180 degree's.

A fast way to check out the thermostat is take a small diameter wire take the cover off the t-stat and jump across the R and the W on the t-stat. If the furnace comes on then t-stat bad. Let me know if this is helpfull. Ken
