New Cozy wall heater not working properly
Natural gas Cozy Heater was installed brand new Model W355F last Wednesday. It worked for a day then stopped working. Pilot stays on but when you turn the thermostat up nothing happens. I decided to replace the thermostat because the one the heater came with was very cheap and I thought it may have been the problem. Heater worked fine for 3 days straight with new thermostat. Now it is doing it again, i turn up the thermostat and it clicks but the heater does nothing. Pilot is on. If i press the safety switch on the furnace it comes right on. I've had to reset the switch a few times now. I don't understand what the problem could be. Any advice would be appreciated.

I presume the safety switch is the vent safety. Was the furnace installed by a dealer or you? Was the vent replaced? Many times I have seen the vents not tall enough and caused the safety to open.

Welcome to the forums.
A fairly basic setup. You can remove the thermostat and touch the two wires together. See if the burner lights then.
It could possibly be a problem with a weak pilot generator or it could be not positioned properly.
Have you considered calling back the installing company ?
They should know the problems with that unit.

The limit switch is Cozy #84166.
Cozy Heating 84166 - Limit Switch 60TG11, L350 --- 1458030657078
I didn't catch the safety switch part in the original post. I was thinking a switch on the unit for operating it without thermostat.

Ok.... now that I understand what's going on.... I second my reply.
Call your installing dealer back. Something is not correct with the flue system.

Thanks everyone sorry it took me a minute to reply. It was installed by a hvac company. And its only been a week and we have had problems with it staying on, yesterday i pushed the safety button and it worked..for a a few minutes. It didn't even make it up to the temp on the thermostat, and then it shut down. I could hear the 'click' from the heater and then it just shut off. Before it stayed on for longer and now it seems like its staying on less and less. The hvac company thinks the vent may be clogged or we need to replace the venting, as they did not when they installed the heater. But the same venting was used for the other Cozy wall heater that was there before this one and it was fine. It is the exact same heater that was there before this one, same make and model. Mbk3 you may be correct, but they are coming back out this afternoon to check out the venting. Pjmax it could be, if its not the venting I will ask about the flue.
