There may be a problem with the propane. Some heaters have a pilot light in the furnace that must be lighted manually. Others have a auto self-sparking unit that will light the propane. And another possible issue is that either the propane may be turned off at the tank----or the propane has air in the lines. Try lighting the main burner on the stove. Sometimes it is necessary to "bleed" the propane lines, I do this with the stove before trying the furnace. Furnaces will blow cold when initially started, then after a few seconds you will hear the propane light, then a few more seconds before they blow warm, then eventually hot air.

You need to provide much more background information: has the unit worked before?, age of unit, was it just installed?, what kind of furnance?, etc.

Try it in your auto, if it cools then itis the transformer, if neither cool problem is probably with the cooler. I've replaced the first cooler and on my second I did above and had to replace the transformer. Now all is working.

Mine turns on but makes a lot of noise. The fan is evidently going out after only 3 months. I am not happy with this heater

Sorry I cannot help you there. When I bought mine I am not sure if the fan was defective but when I turned it on it bearly, I mean bearly blew any heat, so I sent it back to Amazon and did not get a new one.

Don't use mine very much, but never had a heat issue. If the switch isn't working I would return it.

Peggy, It goes into an over heat mode and needs to cool down. Unplug it for a few minutes and then plug it back in. It should be good to go.

Make sure your bedsread is heavy enough to hold the heat. also if you are not in the bed and put your hand on it it won't seem warm. Mine was warm enough but the controller kept blinking and shutting of the heat. I replaced it with a Biddeford which doesn't seem very warm. Oh well.

Yes, you can try manually unplug wire cable that connect to door actuator then use screwdriver rotate opposite way, then turn on ac you will feel the cold air.good luck

it has an overheat protection circuit built in inside regulator box. when there is a surge which causes heat, it cut off power automatically. after the problem is removed, temp is down, it will be back on working.

Not sure what would cause this problem. I would contact a heating company with experience with these units.

I believe that means it's overheated and has tripped an internal safety breaker switch. It should reset itself when it cools down. Make sure there is nothing obstructing air to the unit and that the blower fan is operating ok.

Probably a defective unit. Not holding heat--or not getting hot enough. Ask for a replacement. A reputable company will gladly exchange if within the warranty period

It could be the automatic thermostat cycling on and off. This unit is not designed for continuous heat output.

Good Luck, the 1st cooler we bought from Haier it didn't heat up. So they shipped us a 2nd one and that one didn't get cold. The 3rd one was cracked. After that we just went elsewhere. I would check to see if the thermostat is up? There might be a switch to activate the coldness

Hello,Yes, sometimes it is the case and I know it is normal. But not when you transfer the unit from room to room or turn it on in the morning and it just won't turn on. Last time it took more than 20 min for the unit to come on and it was freezing! Something is definitely not right with the thermostat here.
