intertherm MAC 2460 troubleshooting
Posted: Sun Oct 11, 2009 12:02 pm
I have the above electric furnace and I need some help troubleshooting it.
I was able to make the unit work by jumpering a couple of the wires. I know this is not safe but so was freezing and I didn't leave it unattended. I have a meter and I have 240 volts to and out of breakers and to most of the wires on most of the components in the control panel. I need to know how and in what order to check the individual parts such as limits and sequencers.
I have 29v from the transformer. There are four sequencers mounted on a metal assembly that seems to have a heating element in it. I kind of suspect that this element is not heating up. I assume that the sequencers will not work till a temp is reached by this element. Is that correct and could it be bypassed or is there a replacement available?
