Carrier RTU No Heat Internal Control Fault

Intrnal lockout board code fault applejack cinnamon toast. That's definitely a bad canooter valve. Write it up 😎👍

Hate when guy are too lazy to clean up their mess. Had a Carrier do the same thing with internal control fault. Replaced board. Day later same thing. Thinking bad board . Talked a guy at Mingledoffs , we buy Carrier units from them. Turned out the Effect switch was going pad. Showed me best way to check them. Glad I don’t have to work in the cold and snow much. Enjoy your videos.

Sweet

That’s a cold one brother! Thanks for sharing! 👍

Good one Ryan 👍

Nice job man! Those retaining plates always go first.

Not only faulty hall sensor but a faulty gas valve causes 8 flashes. Most times it’s stage 2, pink wire on valve. Should have jumped W2.

💫💫💫

Good idea to change p.s. and sensor with board low cost

Get the heated gloves man

Great video buddy keep up the good work!

I had a new board give me that control fault

Heads up, 2 stage gas valves on carrier rtu have been failing alot lately 😕 midwest at least

Thank you !!!

We have 2 identical units big 16s code 8 wouldn't reset after several trys replace LGC board like book said still code error 8 whats up anyone

Mine only has one contactor and reading 8 flashes

I’ve come across 2 GrandAire RTU’s new installs throwing different error codes like internal control fault, pressure switch fault, high limit fault, rollout fault. What’s going on? Anyone have experience

Check airflow. Some customers shut vents off in the building.
