Blower works fine and I do have a voltmeter and can do hands on
The difficult part here Tim is that the heat seem to come on intermittently and blogs I have read feel that the relay is a common problem with this particular unit series.
Is the sequencer the same thing as the relay and where are they located and what do I do to solve the problem?
From looking at the manual it shows the sequencer AS a heat relay.. To identify it, there should be a low voltage wire coming from common on transformer to one side of the Coil on the relay (H). The your white wire from thermostat should be going to the other side of coil on relay (H). Then coming from breaker should be a power wire to M1 and a wire to the element to M2. a power wire from breaker to M3 and then wire to second element to M4/ If more than 10kw heat installed,same scenario for each strip/Power wire to M3/M5 and element wires to M4/M6. Once youy locate it, get the part number from relay and Google to find online or take to local parts store .Turn power off to replace relay of course.
