Check to see if contactor is pulling outside. Pull the cover off to see if contactor has pulled in. You may have bad contactor,capacitor or no power to the outside unit. Check breaker. Sometimes there is a float switch inside that may be tripped.Russ

I have a older Intertherm heat pump that has quit heating but still cools alright does anyone have any suggestions what could be wrong??


Check your reversing valve, When you set your thermostat for heat the reversing valve circulates the heated freon through the air handler instead of the cooled freon. The valve is called many things but it reverses the flow of freon See http://www.google.com/images?hl=&q=heat+pump+schematic&rlz=1B3GGGL_enUS329US330&um=1&ie=UTF-8&source=univ&ei=npcOTfLEPMO88ga4poDGBQ&sa=X&oi=image_result_group&ct=title&resnum=2&ved=0CC4QsAQwAQ&biw=1024&bih=576 and look at the different schematics

A/C WILL NOT COOL BELOW 83 DEGREES


Hi, could be lack of freon, or motor for refrigeration on roof is short cycling(switching of before cooling, but first check freon(gas) in a/c, could also be faulty thermostat, you can bridge thermostat, open thermostat and if there are two wires connect then and see if cooling get colder, if thermostat are heating & cooling, don't bridge wire, you will let me know brand & model number, of thermostat so i can tell you which two wires to connect. but first check freon(gas) in condenser on roof. good look.

Air conditioner shuts off early.


Hi, thermostats is not problem , it's asking for cooling when it should, it's your condensing unit outside, if mechanics said, system is o/k. then it's location of condensing unit, check location of your condensing unit, in relation to direct sunlight, condensing unit best location is always a cool place, preferable away from direct sunlight, check to see, when unit is doing that, if it's expose to direct sunlight, that could be your problem, direct sunlight for long periods could cause the high pressure & temp. controls malfunction. or maybe system is not fully charge with freon, double check freon charge. if direct sunlight is your problem, build a shade or change location of condensing unit, good luck.

Solution for ''What turns on the fan that cools the air conditioner condenser on a 2001 BMW X5''


hi, it could be control by thermostat, relay. but first check fuses. low pressure cut off, could do that too, if there's not enough freon in system, it won't come on, check freon pressure or electrical relay, thermodisc, thermostat etc.

Air conditioner does not kick on when I turn down the thermostat


What kind of a unit is it? Is it integrated with a furnace in the attic? Need to now this information. Also, turn the thermostat to Cool/Auto and go outside to see if the condenser unit is running, if so, then there is a problem with the indoor blower motor or thermostat. Jumper the green and red wires on the thermostat and see if the blower comes on. If so, you have a bad thermostat. If not, you could have a bad fan motor or capacitor.

Air conditioner is not cooling. The fan is running. When I turn the thermostat past 7, the unit shuts down. Any ideas? Low on Freon?


Sounds like a leak to me - if you have a set of guages available (know anyone working in the refrigeration field???) you could tell this for certain.  Otherwise, try running it when it cools down outside and see what happens.  Take a stick thermometer, and put it in between the fins on the INSIDE condenser coil.  If they get cooler, but not down to about 50 degrees, then you are low on refrigerant.
Good Luck!
