My wife said the pump timed off and the heater was heating. She shut the heater off and restarted the pump and now the heater won't ignite. The red light blinks three times and I am not sure how to get it to heat again.

The fan will continue to run for a few minutes after the pump turns off to purge exhaust gasses.If it was still heating you have a problem. To reset the heater,turn off the pump breaker for 30 seconds. After that you need a repairman.

Your bypass valve is bad. Probably because you did not pay attention to your water chemistry. It is located where the pipes enter the heater. You remove it from the side of the manifold that is outside the heater. It is not a difficult job. Just make sure your pump does not come on while the heater manifold is open!

Sounds like the igniter needs to be replaced. It is normal for a heater to run five or so minutes that means the thermostat is working. then restart when the temp calls for heat but if the igniter does not work it will not light up again.

Tappan furnace blower will not shut off and furnace does not heat and red light is blinking one flash constantly.


Usually when the furnace blower motor runs all the time
The limit switch or rollout switch is usually open or bad.
The furnace board is seeing that one of those switches is open, so it brings the blower on to try to get the heat out of the combustion chamber area, so the switch will close. But if the switch is bad and won’t close, the furnace board will keep the blower running continuously.

Laser 56 - leaking fuel at heater feed through


Sky,

It sounds like the igniter is no good. Everytime you try to start the stove the fuel pump puts fuel into the burner. If the igniter works it burns it out, if not it just builds up. If it gets high enough it comes out the igniter. Now, there could be another reason for the fuel. Have you ever pushed the little red putton on the sump? I will say, do not push that button until you know what it does. It can flood your heater big time. Rule of thumb for the red button, one time for one second, only.

You need to sop up the fuel from inside the burner. Use a rolled up paper towel. Once you have proved the igniter you can try again. If you can't prove the igniter you need a new one.

Igniter lites up fan kicks on and within 5 sec shuts off


Dustin, The ignitor only glows for 5 seconds, just long enough to ignite the fuel. The heater is shutting down because the photocell does not see the correct flame color.
Since you say "comes on for 5 seconds", I can only assume that there is a flame. You do not specify a lack of flame. I am also assuming that you have had the heater running this heater season and the problem just started.

YOU must find out if the problem is fuel delivery related or electronics related. Start by checking the pump pressure.
