    Carrier 48TC

    Have a Carrier 48TC that is having 2 blink limit switch fault then eventually 4 blinks. Both the roll out and limit switches are working and the indoor fan motor seems to be turning fine. When the unit is power cycled it starts and fires in the correct sequence. After a while the high temp limit switch opens with the 2 blink error then once it does it multiple times it gets the 4 blink error. When i find the unit in this state, only the inducer motor is running. Mod# 48TCED08A2A5A0A0A0 Board # LH33WP003A.

    Anyone have any ideas?

    Thanks,

    Troyblt

    Not the way to get assistance on this forum.

    You are mostly to blame here, as you posted your question in the wrong forum. This forum is for commercial equipment owners to ask non DIY questions.

    Your profile states you are a tech, so if you want assistance, please click on the small black triangle at the bottom of your thread and ask to have it moved to the "Tech to Tech Chat - Commercial" forum.

    Please play nice when you get there, and go into further detail on how you determined the limit and rollout switches were "working".

    Whoa, take it easy. You posted your question the equipment/Building owner section, where tech aid aid is not permitted.

    Moved this to Tech to Tech for you.
