That's an easy one to find if it is overheating. Open up the unit and get it powered up. Get yourself a can of Servisol Freeze Spray. When it stops working spray a part which you think might cause it. Do this one part at a time, or you might get a faulty outcome. If the application of spray on a part brings it to life, you might have found the part. To be certain, heat it up with a soldering iron to make it switch off. Then try the spray again. If it does it twice then replace the part.

Oven has stopped heating, and automatic interior light has also stopped working. Fan still works though - any ideas?


Stove possibly has a fuse panel which is usually in the inside area of the switches and there is usually one for each burner as well as the oven. Make sure you replace with the right size fuse or you could have trouble.

I should be a spokesperson for the "Haynes manual", I have come to find out that's the best book for any vehicle owner. It actually tells you exactly what the codes are for. You can get one st any auto store like advanced auto,auto zone store. It goes by the year and model of your vehicle and it like my car bible, it tells you so much about trouble shooting,trouble codes and how to replace and tear down everything.

The heater does not work, no heat


The relay to the heater coil is probably bad. Depending on how old your unit is will determine if it's worth repairing. Typically, this problem seems to occur after 2 to 3 years. Usually caused by a build up of dust and lint on the heater coil. Often time, the heater switch also plays a roll in this. Check out the Dimplex website for trouble shooting this problem.

I have a 15 year old Coleman Propane 130,000 Btu force air furnace, Model #BGU13020 forced air furnace. Afer the unit runs for 5 to 10 minuets, the flame will start to shuter and then it will trip the heat...


DO NOT attempt to repair this yourself. LP gas is a very unforgiving gas. Sounds like your heat exchanger is plugged. Yes it can be removed and checked, BUT it is not recommended. Trust your local repair tech. Any heater 15+ years old should be discarded.
