Hi. Thanks for replying. I don't know off hand the make and model of the furnace but the RV is an 84 Rockwood. It's not blowing cold air, it's just not blowing at all. Do these things have fuses or something? Thanks again.
Just a thought. A friend of mine here in the campground had a similar problem and after a lot of heartburn and headaches he found that the GFCI was bad. He replaced it and now has a furnace, Fridge on A/C, ETC.
Make sure your GFCI is not tripped or bad??
GFCI is a ground fault circuit interrupter. It trips like a circuit breaker to prevent shock. They are more sensitive than a breaker and aren't reacting to the amperage being drawn like a breaker. These are the outlets you have next to the sink in your kitchen and bathroom with the test button and reset button. There may be one in the circuit that is powering the furnace. There are 12V fuses for the coach accessories somewhere too. If you don't have the manual, happy hunting.
If the GFCI won't reset then it probably should be replaced OR you may have a short somewhere that is tripping it. By the way, the GFCI has two buttons in the middle (one for test black and one for red reset or vise versa, can't remember (getting old)) that is Krazeehorse is right about the fuses and/or circuit breakers. Check them all to make sure none are tripped.
