    Carrier 30HR Relay Board

    I have a carrier 30hr-100r-510. I hooked up an ice cube relay to the alarm terminals to start a light, however, I neglected to notice the manual's note that the alarm circuit is limited to 75mA . Needless to say, I blew something. I priced a new relay board (youch!). Anyone know if there are fuses on this board, or if a relay can be replaced individually? Any help would be much appreciated.

    What was the coil voltage on your relay?
    UA 100

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.
