Model EB10B
The problem I have is that the furnace runs fine during the day kicks off and on keeps house warm. (Mobile Home) Then sometimes in the evening the thermostat shows system on but furnace not running, and like this morning I woke up and the thermostat was set @70 and house was 60. What I have to do to get it to start back up is I switch the fan from auto to on and the fan runs I turn it back to auto (sometimes have to do it more than once) and the heater starts and then runs again good for the rest of the day any suggestions to this problem?

The air coming from the vent is kind of cool

If I have this Model EB10B furnace, What is the model number for the outside unit? The numbers on the plackard cannot be read.
