Hi all, first let me say I have no clue about anything to do with air conditioning
We recently had an issue with our unit causing it to blow air but not cool air. The home warranty people came out and replaced some sort of condenser/compressor and everything went back to normal. 3 weeks later the same problem occurred, they come back out and said they need to replace a defrost control board. I know they did work on the outside unit and said they got it all fixed up. But now my a/c doesn’t have power. And it’s not because of the breaker or the thermostat not having batteries. Is there anything they might have like clipped when replacing this control board? Won’t be able to get anyone til like next week probably so I was hopeful I could find some silly little mistake and fix it with my baby A/C knowledge
