Furnace

My furnace comes on for 30 to 40 seconds and shuts off

Does it light and then cycle off or does it never light?

In absence of additional detail and context, I'll assume your thermostat is set for only a single degree warmer, and you're in a smaller unit that warms up within 30 to 40 seconds.

Is it just the fan that runs, or do you get heat for 30 to 40 seconds? Do your other propane appliances function normally?

I have it set for 5 plus degrees above and only fan runs for 30 to 40 sec. nothing else clicks like before.

Sounds like a bad sail switch most likely

Not necessarily "bad" - could just have an accumulation of dust. Remedy is very easy. It's also a good preventive maintenance item to do before every heating season.

Have you checked to see if you have a "port" that is blowing air right at the thermostat? I've had to adjust those in the past to keep strange cycling down to a minimum. Once you have the right mix, it usual works great.

Without more info we are guessing, but one possibility is the furnace is in safe mode. When the thermostat calls for heat, the blower turns on for a short time them the controller opens the propane solenoid and tries to light the burner. If the burner does not light it huts off and tries again after a short time. After several tries, it goes into safe mode. Make sure you have purged the lines of air by running a stove top burner for a minute or two. Pull the 12V fuse for the furnace and wait a few seconds. Reinsert the fuse and try again.
