Having problems with your Air Conditioners ?

Combustion blower turns on and never stops running

\015 I have a Lennex furnace 80MGF. The combustion chamber blower stays running. I have checked the outlet to make sure that it was not plugged all ok. It will not allow the furnace to start becauce this is always running. I dont know what else it could be. I have checked the wiring and i have checked the wire connections. I can get the furnace to run one cycle by tricking the pressure switch. Please help.\015

Answers :

Sounds to me like the furnace isn't getting enough fresh air for combustion and the pressure switch isn't closing. try taking the cover off the burner assembly and c if that works

Turned on AC was running fine. 30 minutes later began to hear a strange noise. Opened AC/Furnance closet & heard a sound best described as air letting out of a tire. It seemed to be coming from copper pipe. Minute later sound stopped & air was suddenly hot. As if AC was turned on fan not cold. Went outside & neither fan nor motor was running. Turned fan manually. Ran for about a minute then stopped. Outside unit was making what could best be described as a buzzing sound.

I ran a 110Volt wire directly to the ID-Blower to see if it runs independent of the control and it does run. I drew vacuum on both pressure switches and they do

The blower in my Ruud gas furnace won't shut off. It just runs and runs. The thermostat is set to "off" and the fan switch is set to "auto". We haven't used the furnace or AC the past few months since we haven't needed it, so it's been in the off position. Then yesterday out of nowhere the blower randomly fired up and hasn't turned off since. It just runs and runs until I kill it at the breaker. The thermostat is about two years old so it's fairly new.
