Goodman GMV95 issue

I have been contacted by a homeowner asking for advice about a 1 year old Goodman GMV95 that is doing the following:

1.The unit cycles through start-up and the igniter heats up, without ignition.

2.The unit will fairly quickly try to start again.

3.The LED diagnostic code is not flashing.

Any idea what the causes can be? The unit was working fine at the end of the last heating season (it's first season).

I will be helping them find a competent servicing contractor in there area.



Settle down! If you were that important, the city would give you lights and a siren for your car

If the igniter is weak or has the wrong resistance it may take too long to glow red and be the wrong temp and color which can interrupt the ignition timing. After 4-5 trials for ignition it will flash a lockout code and probably start the cycle after a 1 hr timeout period. If the gas valve is not being energized same scenario. Is their gas turned on to the house? Had a call once where goofs turned the gas off as a prank.
