My Arctic Fox's furnace warms the place up ok, but when it reaches the temperature to shut down, it begins its cooling down cycle. I guess that is so the furnace isn't 'put away' hot. And its this cool down cycle I have the question about.

At the end of heating, the furnace shuts down for about 1 whole second, then the blower turns on for 90 seconds. Then, it turns off for 1 whole second again then turns on for 90 seconds. This repeats 5 times for a total of 7 1/2 minutes of cool down time. Is that normal?

my furnace doesnt do that,maybe its to blow the hot air around the RV? Did you get an operators manual with the RV for the furnace? I find lots of info in the owners manuals. good luck with your RV

That does sound wierd. After our furnace brings up the temp it kicks the burner off and then blows the air around for about 90 sec. Then it shuts off. Sounds like its got a sensor not operating correctly.

No it's not normal. You have a defective fan switch. the switch is designed to allow the furnace to deliver the heat built up in the furnace so that your house dosen't over heat. the sequence is: The warm air deliver fan starts when this proves then the burner ignites. (if there is a forced draft blower on the combustion chamber this also has to start and prove before the burner will ignite) This all starts with a dmand for heat from the room thermostat. The thermostat has a heat anticepator in it that shuts the burner down before the room reaches temperature. At this point the air delivery fan should continue to run until the furnace cools down. Any cycling of the fan indicates a small differential between the on and off settings of the fan switch.

A smart man can find more than one way to spell a word.
