Hi,
I install Noma 52-2570-6 Model in 2007 but 3 weeks ago I see some problem regarding Heat is not on and fan is working all the time even I put high temperature then I called tech person when he came it start working again somehow and today I got the same problem. Now what I see is before fan start I see furnace pilot turn red for 5 sec. then goes off then only fan turn's on for long time without heat can some body tell me WHY is that happening.

Thanks,
Monesh Trikha
