1st does the breaker trip?

You problem sounds like a defective Capacitor/Contactor or if the unit has a circuit board a fuse has blown. Are you talking about the whole unit or just the outside unit? e-mail me at hvac.tech7872pr@gmail.com if you need additional help

How many tons is my unit?


divide your btu rating by 12000. (1 ton = 12000 btu)
For example - a 24,000 BTU Air Conditioner is a 2 ton unit. 24000 divided by 12000 = 2
A 18000 btu air condtioner is a 1 1/2 ton unit 18000 divided by 12000 = 1 1/2
you can find out your btu rating by looking on the tag on your unit.

AC unit LWHD 1800R won't turn on & test/reset does not respond.


Reverse the wires in the receptacle ,not the ground,this is most likely the problem the way the circuit is set up in the ac unit.Let me know if this helps.

Just put in a new ac unit and replaced a old one. old unit was 18000 btu and the new one is on 12,000 btu I used the same power outlet but the new ac unit starts up but then shuts down and seems like it is...


The 18,000 btu A/C is 230 volts, are you sure the 12,000 btu unit is 230 volts most are 120 volts.
Usually 12,000 btu is the biggest 120 volt A/C you can buy.
