Does your furnace work?

A furnace is a nice thing to have on a cold winter’s morning in your RV. But if you wake up in the middle of the night to a screeching noise or in the morning to a cold chill and the sound of a motor trying to blow cold air on a dead battery (bad news for both the motor and the battery), you know your furnace is saying it needs a bit of TLC.

Like batteries and tires and a lot of other things in your RV, consider yourself fortunate if you get more than five years on a furnace without having to spend money to keep it going safely.

When a properly functioning furnace fails, the odds are that either the motor bearings decided they lasted long enough to satisfy the permanently lubed criteria or a safety device decided it could not longer stand holding the weight of the world away from disaster. You can tell you have a ‘normal’ problem when you call the local RV parts place and, sure enough, they have it in stock for about double what the discount place on the net sells it for.

The screech usually means $120 for a new motor plus a half hour shop time to replace it.

A furnace blowing cold air continuously means that some safety has turned off the burner, a condition called lockout. This could be the device to make sure the blower fan is working or the one to make sure the burner is lit or the one to make sure the inside of the furnace doesn’t get too hot. You can sometimes tell the age of the furnace by how many safety checks they have – newer ones have more. They run about $20 each plus probably a half hour shop time.

There are, of course, other things that can go awry. Mud daubers can clog up the burner vents, Control boards can fail. Wires and connections can come loose. Crud can get into the blower and clog it up. Burners can get out of adjustment. But furnaces aren’t really that complicated so they can usually be fixed without too much trouble, just a big pain in the wallet.

How to trouble shoot your furnace – also a good introduction into the various parts and what they do.
