I have a Carrier Furnace, three years old. Installed a Hunter thermostat last year model 44260 - programable. Electronic pilot.

At least once a day in early morning and evening, the furnace blower will activate, the pilot comes on and then shuts off in about 5 seconds. While the blower keeps going, the pilot and or flame will come on for another 5 seconds and goes out. After about 5 tries all stops. However, the thermostat does not kick on heat as it should and then I have to activate system by either shutting off blower swith on furnace or open and close the front cover to activate blower. I have another emergency switch in hallway, which also activates blower on and off and activates system. If I don't do this, the furnace doe snot come at all. I changed batteries and filter and checked door on furnace but it is secure.Thermostat had done this earlier in season and it stopped but now it does it every day. Once I activate blower, furnace works for about 12 hours with no problem.

Please advise.

Thanks
