Commercial 5 ton carrier heat pump will not turn off when thermastat is off have to take it off the wall to stop

Zamil 2 ton non inverter split type e7 error what is the problem !? ... There is a mode conflict. Some units are calling for heat and one is calling for cooling.

That is a 5 ton RTU

Miss wired or shorted low voltage wiring. Have you changed stat? Animal chewed wires at foundation wall or in attic?

Installed how recently, by whom? Call installer!

Expansion valve is sticking shut

Change the fan .

yes just post the model number and someone will be glad to help you..
fyi if the model number has for example 373036 373042 373048
the o and number after it usually is the btu value...
12000 btu's = 1 ton so a 036 would be a 3 ton 042 3 1/2 060 would be a 5 ton
post the number someone will help you out... another way to find out
carrier which makes bryant units can help you also
a number for ft. worth location is 817-834-4496 good luck to you

these are somethings that maybe causing it to over heat (1) not enough cooling in it.(2) water pump drivebelt (3) Radiator core blocked (4) Bad thermostat (5) fan blades broken or cracked (6)Radiator cap need to be replace (7) Ignition timing incorrect if all fails stop by your local library and get your hands on a Haynes auto repair Manual for your car wish you the best of luck Michigan Man

Are you referring a to an electric furnace providing the heat, the heat pump providing the heat, a heat pump providing heat usually with an auxillary/emergency electric heating unit, or an air conditioner with an electric furnace attached? If your system normally uses a heat pump for the heat normally, there is an eletric auxilliary heater. You'll probably need to turn it on at the thermostat manually when the outside temp gets below 40 degrees. If you have it nice system, it might do it automatically. If you're referring to the electric heater being rated 8 kw, it'll run using 8kw when you turn it on. It doesn't have the ability to change what heat rating it is. If you're refurring to the heat pump system being rated 8kw, you're probably mistaken. A heat pump might possibly consume 8kw to run the system but that can't be a measure of the system's capacity. Heat pump measurement units are rated in tons, but the system will always run at the same ton capacity whenever it's on, provided it doesn't need any maintenance. Some commercial air conditioning and heating systems have to ability to modify their power output based on the outside temperature, but I doubt you're dealing with that kind of thing.

GOto the iside unit itself. and remove the door and look for a terminial strip that the thermostat wires from the thermostat connects to and write down the colors wires and the letters they're connected to and connect the same to the thermostat .... they should be... r--red=power w-white=heat y--yellow=cool g-- green=fan! See which wires/ colors they're not using and bend back! Thank-you-very-much!
