I posted a question about the Ultra sx 90 (Armstrong) furnace not lighting and the combustion blower keeps running. I did clean the flame sensor and no change. I also changed the spark control moduleas well and it still does not lite. I checked power at the control module and is 24V. When it calls for heat, there is power coming up to the control module and the PV terminal only. There is no power on the PV/MV terminal at all. I am sure that power is required there for it to let the gas out. I ca

There was a lightning strike last night, outside near my AC Condensor Unit. The system is not functioning at this time...confirmed that there is power from the house power panel. There is a disconnect on the house near the Condensor Unit, non fused. Any ideas? I assume that I need to go find the AC controller up in the attic near the fan units.

I have a LUX TX9000LC control, connected to a Carrier Model 394GA036100. The controls don't seem to control the furnace or air conditioning. The fan on the furnace runs continuously even when the switch on the control is in the off position. The only way I can turn the fan off on the furnace is to switch off the power to it. I put new batteries in the TX9000LC. No change. Thank you, Ron Casto

No Power Like everyone else the unit was working fine the 1st summer. Pulled it out again and nothing. It powered up for about 30 seconds then shut down. Now no power at all to the control panel. Is there a fuse link, or some kind of auto shut off I should be looking for? I can't say if it still blows hot and cold as I can't power up to find out.

I have a Heat Controller EKTH15-150J PTAC. Of lat,e toward the end of winter here in southern Missour,i the unit while in heat mode has been randomly blowing cold air. Often you can shut off the unit and let it sit for awhile and when you turn it back on it will come up heating again. A couple of years ago I replaced the control board that had been killed by a lightning induced power surge with a RSKP006 control board kit. It has run fine since, until the last few months.

My Carrier Infinity Hybrid Furnace/HeatPump is suddenly not responding. It's been working for a few years, but today it's acting dead. All the breakers are on. At the furnace (58MVB series 100) I hear a light buzz/hum from the control panel that stops when I turn off the switch on the side (or open the control panel access door), and returns when I turn it on again, but there's no amber light on the control panel, and the thermostats and electrostatic filter seem to have no power either.
