Question about Heating & Cooling
Heater will start and run for about 5 seconds than shut down. Does this three times than displays 6 flashes. Help!

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.

There are dip switches on the main board.. When you remove the lower panel on the air handler there are instructions to where the dip switches should be for your units fan control. if the switches are in the correct configuration.. The Thermostat may be malfunctioning or not wired properly. and last.. and most expensive.. the motherboard may also be failing.

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

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.
