Having problems with your Air Conditioners ?

I am replacing a four year old Bryant thermostat (7 wire) that runs a Bryant heat pump and gas furnace. I connected the Honeywell EIM to the old wires using the same colort codes: W = W (o/b); Orange = W2; Y = Y1; R = R; G = G; Blue = C. When I powered up the system the thermostat accepted programming and setup commands but cannot find the equipment (Error code 089). Help, and Thanks. Ron

I have a problem with my heating system. It is about 10 years old and has had the ignitor, combustion blower motor, and programable thermostat replace in it's lifetime. The system worked great last year. This year has not been so good. The system was checked and cleaned last month. What is happening is the blower kicks in and the burner cut off after a few (15-20) seconds. I tried shuting down system and turning off power to reset. When you turn heater on this is what happens 1. Combustion fan c

I just had a Goodman 4 ton 16 seer system instaled in my home. The thermostat that was instaled is new, but is the old dial type (not programable). At first the tech tried for quite a while to get my original thermostat for a ten seer system to work. I was told that a 16 seer system required a special thermostat. I guess my question is would it be possible to rig the new system to work with a regular old thermostat???

I tried to replace my digital manual Honeywell thermostat that is only 6 months old (new construction) with a programable thermostat. I followed the instructions marking the wires and connecting them up the same way. There was one wire "C" wire that the old thermostat connection said was optional with batteries that there was no place to connect on the new thermostat. I taped it off and left it off. The new thermostat with batteries powered up but the AC would not respond, nor the fan, nor t

I have a Trane XE 1000 and attempted to replace the thermostat. When I saw that the wiring configuration was set up for a different configuration I put the new thermostat back in the box without trying to wire it. I put the old thermostat back on, wired it just like it was (I took a pic of the config before I removed it) and now I can not get the system to power back on. Is it possible I blew a fuse or tripped a breaker in the process of reinstalling the old thermostat? There was one point where

I have a Bryant split system AC that is 18 years old. We have been away all summer (2 1/2 months), during which time the thermostat was set to 80°F. We live in SE Virginia and summer temps are 80's or 90's. We arrived home less than a week ago and turned the thermostat down to 72°F (at all times - we have small children and I am pregnant, so we need the house to be cool 24/7). The system was working fine until this afternoon, when I noticed the house was warming up. The temp had reached 76°

I installed a new honeywell rthl111 series in Oct. 2012. I wired the blue wire to the RC because that was how the old thermostat was wired. The heat worked all winter but when I tried to change over to cool nothing would work. I checked the schematics online and realized I should have installed the blue wire to the B. I checked the fuse in the power panel and saw I had blown it. I changed it and rewired the thermostat the correct way. I tried again and still neither the cool or heat will work. A

I have a Carrier Standard Programmable Thermostat dual zone system heating / ac. I just moved in a month ago, and have inherited this system. At least once a day I find the 'time' display flashing on at least 1 of the 2 thermostats, as if power was lost. I can't find anywhere in the manual as to why this happens. Is it really because of lost power? If so, why is this happening?

I am trouble shooting a Bryant Hi-bred system that uses an air cooled heat pump with high efficiency gas furnace for backup and low ambient operation. How does the system decide whether to use the air cooled heat pump or the gas fired high efficiency furnace. It appears to be outdoor air temperature related, but I can't find the setpoint for it. The main zone Bryant thermostat appears to control the system, but it doesn't always bring the backup heat if the heat pump doesn't function.
