Why do I have to have the flame sensor switch cleaned 2 times per year (the furnace will not turn on properly if we dont).Post created: 2016-02-22 Type of Equipment: Furnace Views: 220

Our furnace room is very clean - we clean our HVAC system every 4 years and regullarly service the furnace and AC.

I am not sure why the sensor is constantly in need of cleaning. I noticed you didn't mention the frequency you change your air filter. Many systems run poorly due to dirty filters. According to the owners manual you should check your filters monthly. Here is a link to the manual, filter information is on page 5
