My Amana Furnace runs about 2 and a half minutes then the flame shuts down.The fan will stay running for about 90 seconds then the furnace will relight and run another 2 minutes. then the fan will run another 90 seconds the shut down until heat is called for again.
-   I have the same problem with my Amana furnace. Furnace cycle starts, flames go, then stops, and repeats cycle several times until furnace "gives up." The flame detectors have been replaced a couple times by the local HVAC Co. but shortly after the 1 yr warranty expires, the problem recurs. I suspect the flame detectors are toast. Also, this causes the igniters to cycle WAY more than they should, and they start to degrade, too.-   dietrich284

Mod#BLU100K948A The 2 selenoids on top of gas valve click when they open (normal). Sometimes they work fine, sometimes they have a rapid clicking noise and do not open the gas valves. Furnace just runs and blows cold air. How do I find what causes these valves not to open.
