    Carrier Heater blowing cold air
    Hello,

    Everything was working fine and then today my heater is blowing cold air.
    I have Carrier Model: 48SX-036080321AA and not sure yet, if there is any error lights on the electronic board, as my unit is in top of my 2 story home and the roof is little ice as is around 28'f this morning here.

    So any advice on this matter? What could be the problem?

    Few pictures of my unit see bellow.

    Thanks for any advice!Name: 20150731_084016.jpg Views: 840 Size: 2.08 MBName: 20150731_084039.jpg Views: 946 Size: 2.34 MBName: ac heating (1).jpg Views: 1062 Size: 1.27 MBName: ac heating (2).jpg Views: 1297 Size: 1.24 MBName: ac heating (3).jpg Views: 854 Size: 1.04 MB

    Hmm, I see no error light codes, and now it works. Not sure what happen! Maybe is related to the heater boiler ? Or is there a filter to replace at a/c heating unit?

    Boiler? Looks like forced air to me. Filter is probably in the central return .

    Also from your picture the contact tips look burned. You might want to clean them if enough tip is left or just replace them. Also is your ignitor clean?

    When you had the problem was there any sound coming from the unit like a clicking sound while it was running ?

    The tips are on the contactor. They are seen in the picture with a yellow and a black wire connected to them.
