The blower is working.

I looked at the filter and it was dirty, so I changed it and its working fine. I know you should change them every year but it was only a couple of weeks over the year.

If your blower or fan is not coming on, the upper leval temperature cut-off (safety) is shutting down the burner. Is your blower working?

The high temp switch is bad and needs to be replaced
