Customer Question
Hello, my Amana heater was...
Hello, my Amana heater was installed 7 years ago and has worked great. In the last few months it seems to be on through out the day blowing cool air through the vents. If I turn up the heat it works fine. For some reason the fan is on throughout the day.

Many of these high efficiency units allow the blower to come on to help control humidity even when not actually calling for heat or cool. Some are controlled through dip switches in furnace and some through thermostat.What thermostat are you using?

My thermostat model number is:
1F95EZ-0671PL.
HVAC Technician: airheatman, HVAC Technician replied 1 year ago

OK it does not look like the 1F95 has the humidity control so let me take a look in furnace manual.
