I have a 5 year old Luxaire unit. it was working fine till now... what happens is when turn heat on.. blower works, and all 4 burner will come one for 30 secs.. and then it will shut off... it will try to do this 3 times and it will shut off completely for an hr..
sometimes it will work for 5 mins heat will come and everything will shut off.
what's wrong ? keep in mind.. i know nothing about HVAC.
