Carrier Comfortzone II thermostat blank.

It may be that the thermostat took out the control board fuse, or the control board fuse blowing damaged the thermostat display. Claim on the 5 year warranty or replace it. https://www.carrier.com/residential/en/ca/products/thermostats/traditional-thermostats/zonecc2kit01-b/ ..

My Carrier Infinity System Advanced Climate Control doesn't turn on?

There are some ideas here including checking the batteries in the thermostat. The first thing to try is a full power reset. Turn off the power at the breaker to everything. Wait 30 minutes and power it back one. Then wait 10 minutes for the self test to complete. https://www.google.com/search?q=Carrier+infinity+system+doesn%27t+turn+on ..

Apu starts fine but no

Hi there, Would this be a preheat / comfort pro APU? If so I would start with removing the top cover on the APU. There will be a fuse holder with a 20 amp fuse on the back wall on the left side of the APU above the APU controller. Check and see if the fuse is blown. If it's not then the CCU board under the bunk/ bed isn't seeing power. Either 12v harness or the communication harness both from the APU controller to the CCU board are rubbed on the frame, or the CCU board isn't transferring power properly. The CCU board is under the bunk. There are 4 3/4 bolt's that hold the lid on. Start the APU and look at the board you should have green light's light up. these light's are called input light's. Then chose a function on the driver control panel as in heat, a/c, low or high fan and see if they come on. If the driver control pane are showing the function on look down at the CCU board and see if there are orange light's on. these light's would be your output light's. There's a lot of cause's for this problem if you need further help feel free to ask. Thank's

Carrier air handler blower won't stop running, even if disconnected from the thermostat..

I have found that turning off all power for a minimum of two hours will reset most errors,. When you switch the breaker back on, you will hear relays clicking as part of the self testing. Wait 15 minutes before operating the unit.

How to connect a six wire blower motor to a four wire blower motor.

It is not possible to directly connect a six wire blower motor to a four wire blower motor because they have different wiring configurations. However, you may be able to modify the wiring to make it work, but this would require a thorough understanding of electrical circuits and potentially void the warranty of the blower motor. If you are not familiar with electrical systems and wiring, it is recommended to consult a professional electrician or HVAC technician to ensure safe and proper installation. They will have the necessary knowledge and expertise to assess the situation and provide suitable solutions.

My AC Carrier unit is blowing 110 at vent set to cool 68 degrees ambien temp 88 degrees.

Low refrigerant levels (most common cause.) it sounds like your outdoor unit is running, but the AC is blowing out hot air, start with cleaning the condenser coils. Spray the coils with a water hose, clearing away the loose dirt and foliage. If the AC continues to blow warm air, call an HVAC expert for help with refrigerant levels.

Carrier Heat Pump Model 25HBC336W0030010. Does anyone have access to service/repair manual for it please?

Carrier says they carry them on their website. Really though, you need a qualified engineer with gauges and refrigerant gas. There isn't much you can do yourself. https://www.google.com/search?q=Carrier+Heat+Pump+Model+25HBC+service+manual ..

Horizontal louvers

Get yourself up to the machine on a safe platform. Remove any covers that will come off easy, or tie them up out of the way. Remov e the filters. Often the whole front can be removed by just taking out a couple of screws. Once exposed, look for something out of place. Put the louver back where it belongs to see how the hinge works. It may have jumped out of it's proper position. Ease it back in position and check it for freedom of movement. If it looks good, put it all back together.

Carrier package unit has constant 24 volts going to fan relay, even when the thermostat is off. Is this a bad control board?

I would suggest first removing all thermostat wires from their terminals on the control board. Does fan relay coil de-energize? If not, likely control board problem. Look for stray metal small pieces of wire or screws lodged on or beneath control board before totally condemning it. If the fan relay coil does de-energize, start narrowing issue down by connecting thermostat wires one at a time starting with 24v Red, then 24v Common if present (Brn? ), then Cooling Yellow, Then Fan Green and then Heat White. It could possibly be a short in the thermostat wire.
