We have a FR hybrid - 3 beds. The unit is just a few years old and the furnace (7920 hydroflame/Atwood) appears to be short cycling. It will run for a minute then turn off, fan blows, then restart and run for just another 30-60 seconds. This cycle continues But it never gets to the set temp and turns off. It has one vent at the front of the furnace where the air comes out.
Recently took it to the dealer and they indicated the high limit switch and thermostat were ok - so i'm assuming that checked out. They indicated it could be ducted to a 2nd location to get some of the hot air out more quickly, but couldn't guarantee it would fix the problem.
Any suggestions for what to check? or other other possible fixes? Very frustrated and would like to have my heater available for spring/fall camping as box heaters only do so much.
