Clothes not getting dry

Turn off your breaker then back on. The check wiring at the back of the dryer .it could be burned there. Next your element may be burned as well. Look for a break there. Last check under top a d locate a disc the shape of about 8 stacked quarters. Bind the 2wires together and if it works, there is the problem. Just replace it. It is a critical piece.

The heater literally stinks for some time after it is installed as the fire tile burns in. Every heater we install makes my eyes burn if I get a good whiff of the fumes...Are you certain the utility actually tested the discharge air? My guess would be someone walked up and gave it a sniff and over-reacted to what is a normal odor from a new heater. You can of course double check your flames from below the burner tray. If they are nice bright blue standing 2 - 4 inches tall your heater is operating normally and the smell should subside shortly after it gets some steady use.

Doesn't seem to heat up as well as expected. I did have to change the outlet for the heaters plug. can run for hours and still be able to tough heater grates.

If this is an old unit you can try cleaning it with compressed air and a blow gun, blowing air forward and backwards thru the ceramic until it is clean. Please do this only when it is off and unplugged. If it is new I would return it these from Dayton are not cheap.

The temperture will vary aprox 6 degrees is there a way to keep it more consistent

I have a problem with a new heater doing the same thing, in my case it is simply that the thermostat is not exposed to room temperature more directly, what I mean is, it needs to be more external and not encased in the heater housing so much. This sort of sounds to me like what might be happening. For example, mine works fine if it doesn't have to respond quickly to changing temps in a short time and reacts very slowly to these drops in temps. On the other hand I can put it in a room and set it, put a thermometer in there and in will regulate the temps constantly as long a window or door isn't left open to cause slow response to show up. I know this may not make sense but it is the case in my case I can assure you. My suggestion therefore might be to look for a external thermostat that can be used with like the torpedoe heaters, electric heaters, light bulb if you wanted to help warm a well house, whatever you need to plug into it and this would then be up to the task of perfect response to these possible temp changes. Then just turn your built in thermostat all the way up and plug into the external type. I have had one of these thermostats going without flaw every winter for about 14 plus years without fail. Mine is set to just above freezing at 34 degrees for pipe protection and it is always hanging there with dust and all, pretty well made, extremely durable! Ready Heater has em not sure of all that carry these but they have a small chain attached so you can hang them on stuff.
Basically I'm saying the built in thermostats ****!

I need a new electric motor that powers the fan. Grainger said there was no replacement part available, but I find it hard to believe I must buy an entirely new heater.

A motor is a motor, if it is more or less same type, size and exact voltage & wattage and you can make it fit... then your all good.

Broken spade on thermostat. No replacement

Could you "Burrow in" and solder a stiff wire wire onto it? take the wire and join it to the wire you need?

Portable heater blowing smoke on start up

Sounds like it is not burning all the fuel . If you have the manual it should tell you how to adjust air flow so it will burn wright. You might need to clean the nozzle that the oil comes out of. The manual will have the cleaning steps to if you have manual. If not i can try an find one for you.
