A constant red light (not blinking) indicates that the thermostat is not calling for heat. Of course you know it is but just to be safe, jump out R and W on the board. If it continues to do the same as you indicated, replace the board.

Take the top off of the heater and and clean the nozzel orifice, while you have it apart wipe off the photo cell and clean and regap spark plug. The nozzel unscews and you can clean it with a bread tie.

After this clean or change the fuel filter in the tank, and finally check the pump pressure and make sure it is inline with the owner manual. This is assuming that it is firing to begin with

SOURCE: furnace shut off after 3 time flame from pilot

Sounds like you may have a weak or bad flame sensor. If the circuit board does not sense a good flame it will not light the burners. Also if your furnace is 5 yrs or newer it should give you a fault on circuit board in the form of a blinking or a code itself.

My furnace runs to operating temp on thermostat shuts down then within 30 seconds try's to cycle back on three to four times. What would cause this.

Some thermostats have a swing setting that can be adjusted. A swing is the setting when you want the furnace to stop or start from the desired set point. For example, you set your thermostat at 70 and the swing is set at 10 degrees. Then the furnace will turn on 5 degrees below 70 and shut off 5 degrees above 70. Check you thermostats manual if it has this option.

Need your model # to check the codes but, this coming back on after turning the t-stat off is rare. You may have been in a lockout and the furnace re-started. Some furnaces try to start three times , then lock out. Time out, then re-start. The codes should be on your furnace blower door. Write back with this info and i could help.

You are on the right track. I would suggest you change the sensor though as if it has failed it would be one of the reasons why it is shutting down the way it is as it cannot detect the flame and is closing the solenoid.

Hope this helps,

Best regards,

Most furnaces have a tech manual inside. Under the blower cover should be a trouble shooting guide. Call the dude and tell him what the problem is.

Furnace starts properly, then shuts down, led flashes 8 times

The first thing to look at is the flame sense rod.
Shut off power to the furnace, remove, clean sensor with steel wool or sandpaper then reinstall the sensor. Reapply power and it should run properly.
