A thermostat versus an AC problem

I have an error message on my Bryant comfort zone thermostat which states "outside sensor error". Does this mean that the AC needs to be serviced or that the variable speed furnace/comfort zone system needs to be serviced?

Hi,

"outside sensor error" is indicative of a Diagnostic error display, a feature where the device checks the functionality of each attached component. It would seem that your system has the optional "Outdoor Temperature Sensor" (probably P/N TSTATXXSEN01-B). The error then indicates that either that sensor is faulty or the hook up cable is unplug or defective. If you do not observed any critical changes in the comfort inside your home or the area that your system monitors/controls, then this only confirms that it is external and a sensor problem and does not affect the A/C and/or the variable speed furnace/comfort zone system. Normal faults could be the external sensor to cable connector/terminals being exposed to the elements and would require hard cleaning.

This sensor is not critical to the operation of the system and is optional.

Hope this be of additional help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

The sensor most likely would need to be replaced. I don't have the service manual.

So this is a Ruud - UBHC AC

Problem with AC thermostat


You are correct about the "er" message. Best bet is to check your user manual for error codes and then take it from there. If nothing in book it is possible that the answer might be on manufacturer web site.

Could be issue with thermostat itself if the other zone is being cooled properly.

We have a Bryant unit and the air compessor outside still runs when the airhandler shuts off.


This could be one of many problems which could include a contactor malfunction, thermostat malfunction or some type of short in the control circuit.
Unless you are comfortable with electricity and the use of a multimeter and wiring diagrams/schematics, I suggest you call a professional regarding this issue.

Ac compressor runs, no blower fan. fan and capacitor ok. bryant


so the outside compressor and fan are working good ? If the fan and capacitor check out good then check that the wire from the thermostat for the fan (usually green and tied to grey on a bryant) has voltage and if it does the control board needs replaced because it contains the fan relay

Change out problem


AIR HANDLERS DO NOT ENERGIZE REVERSING VALVE , THE THERMOSTAT DOES THE JOB THROUGH THE O  OR B TERM TO THE OUTSIDE UNIT. IF YOU HOOK UP TO O TERM AND HEAT COMES ON WHEN YOU SET AC ON THEN SWITCH TO B TERM ON STAT. YOU SHOULD HAVE O TERM ON CONDENSER OUTSIDE AND YOU USE ORANGE WIRE IF YOU HAVE ONE. IF NOT USE UNUSED WIRE IN 6 WIRE STAT HARNESS.

Carrier Comfort Zone 2 flashing E2


the e2 error on your thermostat is a problem with the return temp sensor on your system, the only thing you can really do is call a company and replace it, you can't bypass it or remove it cause the system wont run properly

My Heat will not work on my upstairs unit. I am getting an E2 error code on my carrier thermostat. what does that mean?


the e2 code on a carrier comfort zone thermostat is indicitive of the external safety sensors which are located on your units ductwork in the attic. the e2 code are the hpt/ and lat sensor codes. the hpt is the heat pump temperature sensor and the lat is the leaving air temperature sensor. you can pull off the cover of the panel and behind it will actually give you all the fault codes associated with you carrier tsat.each sensor has a certain ohm rating and if its out of the range it will fail. now as to the reasons for failure, the indoor coil could be dirty, filters dirty, refrigerant charge incorrect.
