Well if this month hasnt been shitty enough today my A/C went out. I am clueless when it comes to most home repairs, but really dont feel like dishing out more cash to a repairman. The thermostat seems to be working, the blower turns on, but the outside unit does nothing. The fan wont turn on, it doesnt make any noise or anything. The control board on the furnace isnt showing any error codes. The circuit breaker is fine, in the on position. The unit is about 2 years old. Thoughts?

Have you tried anti freeze?

Warranty?

Covers parts but not service calls/labor

Look for a kicked breaker.

First thing I checked.

Could be out of coolant?

The outside fan would still turn if thats all it was.

Check all the condensation line to make sure it isn't broken. Similar problems occurred to the A/C unit at the shop a while back. Someone had kicked the line and broken it causing it to not be able to drain. Some sort of sensor detected it and shut the condenser off.

I checked all the pipes/lines I could fine and everything seems to be ok.

Been running the weed whacker around it recently?...could be a broken low voltage wire.

No, it worked this morning then just went out.

Do you have a multi-meter ? I'd be checking voltage at the unit then start trying the ole wiggle tests.

Are you getting reading on your digital thermostat? If not probably the mini board.

Check your PM's here in a minute.

Thanks for the PM but I have no equipment nor do I know where to check the voltage. It actually just started working again, but for how long who knows. Can these things just get too hot and overheat, thus turning themselves off? I know they shouldnt and there is probably still something wrong but its working as of right now.

Yes like I said the thermostat and blower seem to be working normal.

Likely a blown capacitor or the compressor's out.

If it started back up on it's own, you either have a high or low pressure switch that is cutting out the 24 volts to the contactor....I'd highly recommend having a reliable company look at it on monday. The heat has just begun.

Never mind. Missed that it came back on. Definitely not either of these.

If it stops again, make sure it should be on, and then use a screwdriver or something to push the fan to make it turn some and see if it gets up to speed on it's own after that.


If it does, it is the capacitor. When the unit kicks on the capacitor is supposed to provide the 'oompfh' to get the fan and the compressor running, and then the feed to the unit maintains it. If the capacitor goes bad, it gets the lower trickle of power, but not enough to get things spinning.


If it does that, the capasitor is likely about the size of a beer can, or a little smaller. It might have 3 or 4 prongs on it, and the opposite side is supposed to be flat. If the side isn't flat, but popped out a little, or even a lot, then that is a sure sign that is what the problem is.
