i was needing some advice on what could be wrong with my furnace. it will blow warm air for a few minutes and then it starts blowing cold air. we had a guy come and look at it two weeks ago and siad that one of our burners were dirty so he cleaned them. and now it is doing it again. we got a new thermostat on it put new filters on it and it still dont work right.. when we check the red blinking light when it is blowing cold air it blinks fast consistantly. please any help would be great for it is colder then heck in this house.

Use a meter and verify that you don't have any open limits. Check across C & W for 24v. If no 24v you have lost your call for heat. Hope this helps. Make sure the flame sensor is clean also. Hard to know without being there.
