Having problems with your Air Conditioners ?

I have an amana rha36b2a heat pump and am trying to hook up a new thermostat. It's a pro 1 iaq t905 programable thermostat. I have hooked up the green yellow white and red (and ran a jumper wire from rh to rc). I also ran a jumper wire from W to Y. I ran the brown wire to C. The thermostat works great for heating but won't cool. When cool is chosen the heat comes on. Help! I know the O and B on the thermostat are the heat and cooling changeover valves but what should I do to connect them if that

A Nordyne air handler, model B3BV-030K, with 4 wire thermostat. Thermostat and AC works fine in "cool". Switch it to "heat" and nothing happens.No fan, no heat.(I have built in heat strips -resistors). I jumpered (on the nordyne circuit board-input from thermostat) from R to W. (24 volts from R to W, which should start the heater. Nothing. No relay "click" like when AC comes on. If i jumper R to Y, AC comes on ok. Does this sound like a relay gone bad on the circuit board? Or what? If relay bad,

I just installed a P474-1100REC & P474-1100RF in place of a Honeywell Thermostat.I have a typical 4 wire 1 stage Cool 1 stage gas heat setup. The new thermostat is not working right. I noticed on the old thermostat there was a jumper wire from R to R1. Do I need a jumper wire set-up here as well? If I do where do I connect to? There is no R1. Please help

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 an old Miller 3 ton heat pump. It will work fine sometimes but when it decides not to work i can go outside and press the power contactor and the unit will come on as long as i hold the contactor pressed. A friend told me the defroster board could be the problem because when its cooler than 45 outside it wont come on by itself. But when i measured voltage at the thermostat no wire had 24volts.When it runs it runs good and cools or heats the house well.

It sounds to me you need just a really good tune up maybe a new contactor retest your low voltage what do you have from common to 24 volts it should be 27 volts if you test each wire you want get 24 v it will be like 7 or so ... Air Conditioners

I installed the rth2310 and it seemed pretty straightforward. I had R, W, Y, G, on the old thermostat, and hooked them up to the same, with R to Rh with the jumper in place. Now, the snowflake cooling symbol is on all the time, and when I turn on the heat, it just runs all the time. This is a zoned system. I replaced another thermostat at the same time, and it works fine (it had a black wire going to Y, but otherwise the same).

Goodman GSH130301AB heat pump with Braeburn 1200 multi-stage thermostat - both less than 1 year old and installed in new construction. Heat can be set at 60, fan on AUTO, with room temp at 70 and heat will kick on and stay on. When this happens, turning thermostat to OFF does nothing - system continues to blow heat - and I can only shut it off by flipping the breaker. This only happens now and then - typically works fine. All wiring appears to be correct though reversing valve for cooling is

We installed a Honeywell RTH230B thermostat on a Trane XE60 Air Handeler this winter. When we put the system on heat it works fine. However, when we put the system on auto for cool the compressor fan comes on but not the air handeler fan. On the air handeler the terminal strip from left to right is R W Y G B/C. The red wire on the R terminal comes from the contactor on the compressor unit. The other wire from the compressor unit is connected to a gray wire that goes to the thermostat. The W

I just replace a Honeywell T87F28733844 Thermostat with a Honeywell RTH221 Thermostat since then my the furnance will not produce any heat. I replaced the thermocouple, but still no go. The pliot light is lit, but still no go. The wires that went to the T87F are yellow, green red and blue. The RTH calls for a yellow, green, red, and white, with a jumper jack in the Rh Rc. The blower for the fan works, and the ac works, but not the heater

I have a hunter programmable thermostat model #44155c and Im trying to wire it to my goodman furnace. Its a 7 wire system with a white,yellow,red,green,brown,blue, and orange wire. The ac works fine but the heat wont shut off. Thanks

Make sure you do not have a jumper between the red and the white. Also make sure the wire is not hanging out from behind the screws. If the heat stayes on no matter what you do. The red wire has to be touching the white somewhere. \015\012The r ... LG LSC183VMA Split System Air Conditioner

I have an Amana RHE30A2B heat pump. I installed a new thermostat, Honeywell, last night and now the coils are not cooling & the unit is blowing hot air. I have double checked all the wiring & everything seems to work as it should. Is there a breaker or fuse on the outside unit that I am not aware of before I call a service man out. We also had an electrical storm last night. It could be a freak thing, but I am still concentrating on the thermostat.

Carrier thermostat Hello, My Carrier electronic thermostat is connected to a heat pump.  It was set to the COOL position during a summer thunderstorm when the AC suddenly began running no matter what the SET temperature was.  It works normally when I change it to the AUTO position.  The HEAT and EHEAT positions work normally. I tried cutting power to the unit for 2 days, after which it worked normally even on COOL, but after a short power failure it resumed the problem of running the AC continuo

I hate to say it but Ive had trouble with Carrier's Tstats doing similar improper things. Unfortunatly the only repair is going to be replacement of the whole tstat. I recommend Honeywell's FocusPRO or VisionPRO tstat. Ive yet to have one fail and th ... Air Conditioners

Reset button for Ruud Achiever 14 heat pump/AC compressor? My Ac/heat thermostat was blowing fan on and would not turn off. I switched it off at the circuit box, and bought a new thermostat RTH221, wired it and it would not blow cool air when on cool nor warm air when on heat. Called the 800 number for Honeywell and tech said I had wired it correctly, to check outside and see if the compressor was running. It was not. This Ruud unit is only 8years old so I'm wondering if a reset button has

I have an intertherm rpbmb030k combo a/c and heat. Had frion put in the unit over the summer and a new digital thermostat. Unit has worked great until we needed heat. Unit works great on aux. heat but keeps switching to to defrost mode when standard heat is on. Switched out the defrost board on the unit to no avail and an a/c guy checked to ensure the new thermostat was wired correctly.

Hi, if the unit had a leak in it, was the leak located and repaired? Did he check the pressures in the unit now? If it switches to the aux mode ( Heat Strips ) is normally caused when your primary unit, compressor and freon are low on charge. I would ... Intertherm P3RA-060K Air Conditioner

Amana PTAC Unit is not producing heat. Fan works fine. can not locate manual reset for heat although a label on the unit says there is one. I have an Amana pth153b35ae ptac unit that the heat will not come on. The compressor will run in the cooling mode but not in heat mode. I verified the switching valve is working and the capacitor seems to be fine as the compressor will run in cooling mode.

Rudd furnace I have a RUDD furnace model UGPJ-07-NAMGR. It had stopped working, so I replaced the thermostat but it is not the thermostat. When I hold the furnace reset button, the furnace will fire according to the setting on thermostat(heat or fan). As soon as I let go of the reset button, the heater stops working. It does not matter what I do to the thernostat, the heater will not fire. I crossed the red and white wire but nothing happens. The heater is supposed to fire when I cross wire, ri

I have a Tempstar model NFCP3600A1 (style # FCP3600A) ICP Heat Pump. Starting last week, the unit kept heating well over the set temperature. I swapped out the thermostat thinking it went bad, but it still continued heating and the "off" wouldn't work at the new thermostat either. Next, I checked for shorts in the thermostat wires and they seemed OK. I then replaced the TI 26FC-2 circuit board. Once the unit heated the house to the set temp, it continued running up to 75 degrees. "Off" and lowe

Still working on our ac inside unit Coleman EB20B outside unit Goodman CKL49-1. We had a short in the thermostat wiring that we repaired. Now the AC is working when the fan switch is on run. It doesn't run with the therm switch on the cool cycle. Have we crossed wires somewhere or is our thermostat bad? Thanks Ken Rohm
