I have a Johnson AirEase Ultra 90. It was set to 21 C today and when I got home it was 18.5 will cool air coming from the vents. I turned the furnace on and off at the switch, and then it came on. The honeywell thermo, was set to 'heat' with the fan on 'auto' The furnace came on for 20 minutes or so, then turned off, and the blower continued for another minute or so as usual. The temperature was 20. I turned it up to 22 and it came back on a couple minutes later, heated for 20 minutes or so and again switched off. The filter was changed last week. Any ideas?
