SOURCE: air conditioning unit not cooling

the problem sounds like a defective capacitor its located on the condensing unit outside, also a contactor that is used can be defective also.

SOURCE: Goodman PHJK048 Heat Pump Package

ok...where to ....the thermostat is just a switch.It will tell the unit to run or not run.if you measure the temp with the heatpump running,the air is warmer than 68 but it feels cool to you because your body is 98.6.The unit will run more often and for longer periods when the temperature drops outside for a few reasons.First,your house has more of a load to heat,meaning you have more heat loss because of the difference in temperatures outside and inside.Second,your heat pump pulls heat from the outside air.The colder the air outside,the less btu's for it to pull.If you have anymore questions Hope this helps,Dave

SOURCE: Heat pump cycling on and off.

It sounds as if you you have a low charge of refrigerant, r22. When the unit comes on outside, the outdoor coils become the lowside, there is a low pressure switch that is tripping out contactor protecting the compressor.

Furnace ignition board HK42FZ2009 fault code 14, already tried lower temp, cycling power and turning heat up. Can't find Fault code.

I googled "carrier hk42fz Fault codes", and the first thing that came up was a PDF that stated led status -ICM controls. Its the fault code sticker that comes with that control board that is supposed to be installed on that unit. It states #14 is an ignition lock out for 3 hrs after failed attempts in heat. Cycling power off should have reset this. If not, best make sure you do some troubleshooting to ensure all else is good like the safeties, connections, polarity, and such. It may be the control board has faulted, but hard to tell from here! Hope this helps!

My Dometic RV AC will not run. It will come on, then almost immediately go off, come on, go off again, most of the time with only seconds between

Error Code E-5 indicates an open or missing temp sensor circuit. Either the remote temp sensor is bad or they didn't plug it in when they changed the circuit board or plugged it in the wrong place.

Operation sequence= call for heat--inducer blower motor--makes pressure switch--signals board to bring on hsi--after a set time gas valve opens and you have ignition--main blower motor comes on after a set time

Carrier OEM to Honeywell Programmable Tstat - NEED HELP

you likely have a "two stage" system, but not a two stage heat pump. the first stage is probably the heat pump itself, and the second stage is the auxilliary resistance heat that suppliments the heat pump at lower temps. if i knew the terminals that are available on the new stat, i could advise you on the proper wiring.

Oven will not come on. I set the temp and screen goes blank after 5 to 10 seconds. Lower element doesn't heat. Oven will broil.

This sounds like you may have a control panel issue. The display going blank and one element not working is what is making me come to this conclusion. You can have the board tested to see if it is faulty.
Do you have any error codes?

Weather King Heat Pump

Hey kellyrepp -- Three things to check quickly, so many things can be wrong, but i will try to help with the info you gave me.

The first sounds like your electric aux heat is not wired in or not working correctly , this should kick in when the heat pump cannot keep up with desired set temperature. For sure thats a problem

The second thing i would check is that the compressor for that unit is running. It should sound exactly like the one for the upstairs, the fan noise should be like a whrrrr , and the compressor should be a semi loud hummm.

Third feel the pipes on the outside unit that are on the outside of the unit (the unit for the second floor) Let the unit run for 5 minuites. Now check that the first floor unit pipes are the same tempereture. They are about 110 degrees or so, depending on the outside temperatur , be carefull not to burn yourself. If the lower unit is colder , the two most prominent problems would be #1 the compressor is not running #2 Low on freon.

Hope that helps
