Air conditioning broken. Help!!? Our air conditioner broke the other day. We come down and...
Our air conditioner broke the other day. We come down and noticed the pipes were frozen and the blower wasn't working. So we simply went and got a spanking new blower, installed it, turned the air conditioning on, and nothing happen. So... we turned on the furnance, and the blower started working for it. Any suggestions? Do we need to check fuses?
If the pipes were frozen, you probably be low on refrigerant. But which pipes were frozen? You probably wasted your money replacing the blower. You should hold spent the money on an air conditioning repairman. The unit would be working in a minute. Never self-diagnose if you have no idea what you're doing!
Oh sorry, it sounds like your speed relay is out on the furnace board. some are a separate relay but these days most are built on to the board.
You feasible have two power taps going to the connector on the blower motor, I assume you hooked both wager on up.
Generally, when there is a call for cooling it engage two relays. One shuts off the heat so you can't steam and cool at the same time and the other switches those motor taps as cooling is usually at high-ranking speed and heat at medium or low.
You may or may not own needed a motor but it is not unusual for a bad motor to take out the relay near it. So I don't know that for certain.
We know all the fuses and safeties are okay or it would not run within heat.
That speed relay is a more common bomb because the high speed on the fan draws more power than within heat and is more likely to burn the contacts.
Without self able to put a meter on it and see where you are losing the voltage explicitly the best I can tell you.
Good Luck.
Answers: Well because the pipes froze means the compressor be working and it froze because of no air flow accross the coils. The fact that the blower does work on the warmness setting means the blower works. You can turn on blower only on the thermostat ... does the blower come on next? If it does then you could just hand down the blower on until you get it fixed.
It sounds like the controler surrounded by the unit might be bad or a loose chain. Make sure all wires are tight on the controller and in the thermostat. That is where on earth I would start. Fuses are not the issue here.
