    Hope this message finds everyone safe and well. Long story short - purchased a home back in 2021 that was to be gutted and remodeled. Due to some structural issues, work was halted and I just haven’t given the project any investment (time or money). Before stopping, a reputable local AC company...

    We have a Carrier furnace (59TN6A) and air conditioner (24ABB3/24ABC6) paired to a Carrier COR 7C (TSTWRH01) thermostat. The outside temperature reported on the thermostat is incorrect...mostly only happens in cold weather. For example it is 28 degrees F outside right now but it is reporting...

    I am close to springing for a second story ducted mini split without supplemental heat in climate zone 5. The outdoor unit is a Carrier 38MARB 1.5 ton HP. I have spent a lot time researching this project but I had ignored the defrost function. Now I feel like Jessica Simpson because when it...

    I understand that for most thermostats, the temperature sensor is within the thermostat itself. I purchase a new home in October that has a carrier system. I noticed that in the winter, as it got colder (almost always happens only when outside temp is below 30F) the system stays on well past...

    I have a carrier infinity furnace that is 11 yrs old. It's out of warranty. I had to replace the inducer motor at 7 yrs. That replacement is now going bad and needs to be replaced out of warranty at a cost of about $1500-2000. The company that I use for hvac suggests that I replace the furnace...

    Hello. My furnace displays a 12 fault code. I've replaced the pressure switches, control board, flame sensor, and limit switch, I have a new capacitor and a new ignitor to swap out the respective components. The sequence: a call for heat will initiate the blower, in about 90 seconds the ignitor...

    I went to connect my gauges to a charge port on a Carrier 38MGQC18, and the port on this Carrier outdoor unit is slightly larger diameter than the typical Schrader connection ports I am used to. Is there an adapter I can get to connect to the Carrier charge port? photo at...

    Hello! I have gone through a fair amount of options trying to solve this and it has not been fruitful. I was wondering if anyone on here might have experienced this before, or maybe has a recommendation on what I should try next? We got a house last year with a Carrier furnace. We are in...

    I have a Carrier MCB58 gas furnace and since about two weeks it started making a rattling sound when the heat stops (transition from heating to fan circulation only). The filter is new. The blower is clean. The sound seems to be coming from the inducer. Here's a video of the noise (noise...

    Just had an AC checkup and was told I should have a hard start kit installed. Long story short, yes, I believe any large motor should include a startup capacitor/relay circuit...and after looking over my system, there isn't one installed. I believe the $300 for the tech to install it is rather...

    Hello and happy new year! since coming back from vacation, my hvac is not blowing HOT air anymore. everything was working fine before. it's blowing air now, but just when we increase the temperature, it's not producing HOT air. the thermostats are OK (they're all new from sep 2018), and...

    I have a gas furnace carrier weather maker 9200. It is giving error code for open roll out or limit switch. The blower motor continues to run, there is no power to my thermostat. I have checked the roll out switch with my meter and it shows the switch to be closed and in working order. I have...

    (background) I've got a 7 year old Carrier Infinity system (controller + furnace + AC) - it's working just fine but I've got a question. Is there a way to 'tell' the controller (SYSTXCCUIZ01 .... not the later touch-screen or Wi-Fi units) to only run the air conditioner in 'low-power' (bypass...

    I was trying to install a Honeywell tstat on my Carrier (conventional) split system. The original tstat had an orange wire at the O terminal, but the Honeywell tstat doesn't have this option, unless it is used for a heat pump. Leaving the orange wire off kept the air from cooling (I am assuming...

    Greetings fellow DIYers, I'd like to replace all four heat exchanger cells (Carrier part number 79988-50) on a 100,000-BTU/hour Bryant 394GAD048100 gas furnace. I like the modularity of individually replaceable cells, but it seems everyone is asking per cell what a complete heat excahnger...

    I have a 2004 Carrier 58mvp 120 130btu 1HP Ecm motor, with a HK42FZ022 board. Every time there is a power bump the furnace defaults to high blower speed. The AC works but no heat, I then I have to remove the model plug, switch on sw1-6, run the test mode until code 11 flashes, slide dip switch...
