I have a heil -- model NUGK100DH12-- problem is when power is supplied to it the blower fan comes on right away along with the induction blower and it does have the electronic pilot which all works to thermostat setting. when setting is reached the flame shuts down normally and I think the induction motor cycles correctly, but the blower motor never cycles off. It's on constantly. I tried replacing the fan relay to no avail and am considering replacing the timed fan controller as the next move

Trying to determine whether I have a bad Ign/Lockout or inducer relay board on Mod 58SXA080-GG. If I shut off heat at t-stat or unplug ign mod. for 10 min.

I do have 24V going to relay board when cycle starts but drops out when motor stops (I assume this is the ign module lock out). I checked the air switch by ohming out while

With power on the blower starts as a result of thermostat calling for heat from the unit and after a minute goes on to second phase of ignition with exhaust blower motor initiated. During this phase gas is being brought to the burner that you can smell however burner does not ignite gas. Unit continued with this opera

When we returned 2 1/2 days later, the coils were frozen and no air was comiing through the vents, even with the blower motor working. So I turned the unit to furnace and melted the ice on the coils, but had to pull the fuses on the outside box to get the compressor to shut off. Is there a
