Question about Heating & Cooling
This year our heater has to be turned up much higher to get the same heat level as previous years. We thought the thermostat might be clogged up with dust etc so took the cover off to clean it. When we did, we found that the thermostat bulb housing was just sitting loose above the "motherboard" to the left of the control panel. The label on it says it must be fitted under the unit so we think it is in the wrong position and would like to know where it should be fitted. Also, is this likely to be the reason for the reduced performance or is there another problem? The heater was fitted new but we felt it never worked quite as well as it should have.

SOURCE: Manual required
This is a link to a vulcan wall furnace manual. I'm not sure from your listing if this is the right one but it may help if programming is similar on these units. If not get back to me by posting more details for me here and I will find the right manual for you. Please do not vote on this until I find you the information you need so you can rate it fixya. Thanks,
If this is what you need let me know when you find out.

There are dip switches on the main board.. When you remove the lower panel on the air handler there are instructions to where the dip switches should be for your units fan control. if the switches are in the correct configuration.. The Thermostat may be malfunctioning or not wired properly. and last.. and most expensive.. the motherboard may also be failing.

You need a specific thermostat for a Wall Furnace it is a Millivolt Thermostat and not a 24v standard thermostat....usually it will work anyway however if the powerpile (generator produces millivolts from the pilot light) is weak it may not be producing enough...or the Pilot light may be dirty and lazy...won't produce enough millivolts ...or you can have bad or dirty contacts or connections....or a combination of any of the above.....a 24v Thermostat and particularly a non-mercury thermostat has too much resistance in it for a millivolt system....as your Wall Furnace (other than the fan) runs on less than 1 volt

YOU MUST HAVE THIS THING CHECKED OUT BY AN EXPERT. IT IS A FIRE HAZARD. Even if the thermostat was a closed circuit, the furnace would be working all of the time but it would not be overheating to the point of warping parts. You are either overfiring or your blower is not running all of the time. If it's a blower problem, clean out the dirt and dust and oil the motor. If the motor is not running, replace the fan control or the motor. If the furnace is overheating, your gas regulator might be bad allowing to much gas pressure to the furnace. Also, make sure that the burner orifice's are the correct size for the heater.

Hello,Good job with description.Something is keeping the condenser off(saftey).Do you have an emergency heat setting on the therm.It will run electric heat strips only until service can check it out.Very rare that the disconnect switch (black box) is it.Need electrical meter to prove it out.
