    Coleman Gas Furnace
    I have a gas furnace in a mobile home coleman evon DGAT070BDC. A relay was clicking in the blend air box. I replaced the relay and might have put the wire on wrong. There is five wires, different colors going to the relay, with five numbers on the relay.

    1. how can I get the correct color/number system to the relay

    2. Now the thermostat, digital, goes crazy high(stops at 105 and its still cold in the house) when I turn on the furnace and there is clicking in a relay in the upper control box.


    Thanks

    Ho many wires were on the old thermostat? Is the new thermostat battery operated?

    I did not change the thermostat, it is digital, I only changed the relay in the standard blend air II unit. I need to know which color wires go to the number on the relay

    Order the wiring diagram here. Just tell them what you need on the order form.

    You might also check the part number at this site to be sure you have the correct one.
