Installed a VG7SD-090-35 AIR TEMP horizontally, discharge

Customer Question

Installed a VG7SD-090-35 AIR TEMP horizontally, discharge right, runs OK if burner door not in place, except yellow light flickers. With door in place it short cycles, 2 minutes on 2 minutes off. Bypassed all limit switches, not the problem. Bypassed .9 pressure switch on the inducer it worked with door on , replaced switch, not a fix. Prefer to discuss this by phone Lavern Ransom 1533 Kensington Janesville Wi.(###) ###-####or cell(###) ###-####

Hello,

The company charges extra for phone calls, that is optional, or we can continue here if you do not accept the phone call offer. Meantime I will do some research on your Air Temp unit.

Expert:  Phil replied 1 year ago.

Meantime tell me how long your combustion air intake and plastic exhaust vents are, and how many 90 degree elbows are in them.

We can go from there.
