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.
