Customer Question

How cool is this chat box! Have a split-unit, model #GR4GA-024K072C (believe it's a Nordyne) and it does not cut on at all either heat or cool. There's no noise at all from the unit, have already reset/checked the breaker box. Have tools, will travel LOL

Russ here. Welcome. I am here to help. Please do not rate until you are satisfied with answer. Always available for follow up questions If you have a voltmeter check to see if you have 220 volts to unit if you do. Open electrical panel and check to see if you have 24 volts on terminals R and C on board. Also if not check to see if fuse is blown on board. If it is not blown and you do not have 24 volts. Check for bad transformer. Should have 24 volts coming from wires going tom board. Russ
