Furnace seems to not be blowing very hot!

It is a Coleman-evcon model number DGRT070AUA. The burner kicks on, warms up, then blower kicks on. Around 2/3 of the cycle, the burner turns off high and just the pilot is lit along with blower still going.. Is this normal? The heat from the register doesnt seem to be as hot as normal, although the house is not freezing.

Check burner tube for clogs and also burner orifice/spud behind gas valve for blockage (spider-web-bugs).

If ok, get back with me.


Thanks,
