I have question on my coleman I set the heat to 70's after I warm up the house I set the temp to 63 and when I woke up this morning around 6 am the heating is not working and the temp was 59. Do you know what's wrong with it? I try to on and off main switch but its not working.

Before I can offer any help I have a few questions. Was this a one time problem? When you re-set the stat to 70 degrees does the house heat up to that temp or is it staying in the 50's?

Yes this is the first time happen. Yes when I set to 70 degrees the house heat up and to that temp. usually it's automatically on when it reach the temp I set on. My wife said she heard was running around 3am but the temp on the house is cold when I woke up this morning the system is not working the motor or blower is not even turning. Do you know if the fuse or I have to call the maintenance to fix it. Thanks

It is not the fuse if you are able to reset the furnace. When a fuse is blown it stays blown. I suspect that your thermostat may be the problem. Do you have a stat that allows automatic night setback temperatures? If so, double check the program to insure the stat is calling for a warm temp in the morning. Might want to replace the battery inside the stat just to be sure.
