Question about Heating & Cooling
Call for heat. Inducer starts. Than igniter glows. Than burner lights. Than blower comes on. Then after one minute. Burner goes off. Than blower shuts off. Inducer is still running. After 30 seconds igniter starts again. Total time is 3 to 4 minutes. Over and over and over..
It could be two things flame sencor needs cleaning of conections not tight or the pressure switch is not working try jumping it out and see if it lights

The sensor for the thermostat is probably going bad or has bad connections. It is (or thinks it is) heating up fast and therefore shuts of the heater.

This just sounds like a couple of problems. First, your blower is designed to only turn on once the heat exchanger heats up, so the flame will be on for a minute or two before the blower starts. it sounds like your blower is cooling down the heat exchanger too fast and causing it to shut off so it can warm up again...check blower speed for heat, it should be the lowest speed (black wire). Blue=medium speed, red= high speed. second problem could be your flame sensor rod is calcified, you just need to locate this and clean it off with some fine sand paper.it is located in the flames near the burners. Also change your filters, for proper air flow through your heat exchanger.

have you changed t-stat? if so you need to increase the heat anticipator. if you have a fan limit switch, the setting may need adjusting. Thay will change with age

In the burner compartment opposite of the ignitor is the flame sensor. seems to be dirty. one screw holds it in. Remove and clean with a wire brush.

The problem you have is water in the exhaust pipe.
Check to see if the pipe has sagged anywhere or if there is a trap in the line.
If you hear gurgling then it is definetly water....
Some times can be hard to find, even a pipe 1/4 full will cause problems. They are very sensitive to flue problems.
Make sure that the flue pipe either runs back to the furnace or out to the outside, a continuos slope either way witha high spot in the middle.
Also check the bottom drain of the blower if it has one, have had them plug and trap water also..
I hope that this will help you to solve your problem!
Thanks for using Fixya!!
