YOU CAN HAVE 120 ON EACH LEG WITHOUT HAVING 240 ACROSS CHECK ACROSS BOLTH LEGS.IF YOU HAVE 240 YOU PROBABLY HAVE A SAFETY HOLDING IT OUT.TRACE THE POWER FROM THE CONTACTOR THREW THE BOARD BY HOLDING ONE METER LEG ON COMMON AND WALKING THREW THE CIRCUIT WITH THE OTHER LEG.

I have a raka-037jaz air cond. I was wondering what size is this unit? And if my breaker keeps tripping for the outside condenser does that mean my compressor is workIng too hard and needs to be replaced?...


Hello You have a 3 ton unit with a 10 SEER rating.this unit should NEVER be on a 50 amp breaker.The breaker size is on the model plate/sticker....any way the compressor is shot and it is time to find a new 3 ton condensing unit.espescially if it is TRIPPING a 50 amp.Good luck

We installed a new TCJD36 (3 TON) unit with new A coil. The unit works fine from morning until 4:30 PM. from 4:30 PM to 9:00 PM the compressor does not come on. Inside fan goes on and outside unit fan...


This really sounds like the unit is over heating the compressor to the point of triping the internal high limit switch and just taking that long to cool off before it resets. If it continues to do this go outside and run your water hose over the compressor for at least 30 minutes to cool the compressor down and see if it starts for you then. If so then your unit could be over charged and creating very high head pressures!

Ac unit clicks outside but nothing engages fan or compressor on unit furnace still runs for heat setting and fan still blows but ac will not engage just hear a clicking was running for three days this...


Have you check the outside breaker? If its ok then you got a problem in your electrical system inside the unit probably the contactor is not engaging this is where the 24 volts from the thermostat calls for the 240 volts to run the condenser fan and compressor. Be careful checking this out because of the high voltage.

Compresor wont start and when it does it cycles on and off


Does the condenser fan come on? I am assuming the evaporator fan (inside) is blowing? The way these units are wired is that the power goes the the inside unit and the controller inside sends power to the compressor and condenser fan. But if the controller detects that the condenser fan is not turning (via no ground return) it will not send power to the compressor. This to protect the compressor. Did you notice it trip a breaker? When it is on, do you have 240 on the unit outside but not 120 to ground from each leg?

How do I know if compressor of my house air conditioner is turning on when I start my air conditioner? When I start my air conditioner the fan outside the house turns on, the air is blowing from the vents...


if the compressor is starting there will be a very small dimming in the house lights,if you go outside to the unit and start it from the outside disconnect when the compressor starts you will hear a whine type noise coming from the outside condenser unit that is the hermetic compressor motor operating,no cold air can be a number of issues,low on refrigerant(not likely on the new sealed systems) a bad motor start/run capacitor(quite likely) a bad contactor on the outside unit that supplies power to the compressor,one leg of the 240volts that supplies the compressor power,the fan will run on 120 volts,but the compressor needs 240 volts check the fuses.breaker in the power panel

Have a Ruud AC unit the problem I have after installing a new condenser fan motor when I throw the circuit breaker the unit will not turn on but when I push the contacts on the contactor in manualy the fan...


The contactor engages from low voltage power from the thermostat as does the outside condensing unit. You may have blown the low voltage transformer or have a loose thermostat wire. Check line voltage(220 volts) to the transformer. Check load voltage(24 volts) from the transformer. If no voltage out,replace the transformer. If you have voltage out(24) check the thermostat wires and the thermostat. If you have a digital thermostat there is a 5 minute delay in the thermostat after power is restored before it activates.

Compressor kicks out and it's new


First of all, clean your outside coils so that you are assured of good cooling air. The compressors have an overtemp device that is usually internal to protect them against heat. If you have an air compressor use it to blow out the coils good. If the compressor will start, the capacitor is good so it sounds like a cooling problem with the compressor

Blowing hot air, compressor not kicking on, just fan ? ?


are you speaking of the outside fan or inside? compressor should be a little warm but not boiling hot. the unit could be low on freon. if low it will run a while but the compressor will overheat and shut off leaving the fan running by itself ouside. if nothing outside is running check power. if you have power check the contacted outside to make sure it's pulled in. contacters are bad about going out on goodman untis. Also ants can get under contacts.

Have a near new panasonic cs-e28hkr split system air conditioner and the outside condensor fan continously runs even with inside unit is turned off? Thanks


Sir/madam,
If the inside unit (evaporator) is turned off absolutely.
The condensing unit must be turn off outside because the power
are derived comes from the evaporator.
Possible it seems on the cut out stage inside and remain the power still on
Otherwise theres somebody tamper the connection?

Fan cable consist of 3 wires
1 Common line
2 Start /stop line***Change the connection of this wire where it located, To On/ Off switch of the
evaporator inside unit
3 Ground green line/Earth

note: you can get all that wires inside the power supply in evaporator area.

If still under warranty inform the manufacturer

Ruud achiever 10 seer air conditioner


It sounds like your condenser fan motor may be locked up or the capacitor that helps give the condenser fan motor a kick to get it started may be defective. Try turning your system on and using a long screwdriver try to push the fan blade on the condenser fan motor to see if it will run normally if you give it the starting boost it needs.If it does run at full speed and doesn't over heat or start and then slow down then you probably only need to replace a simple 10-12$ capacitor. If it barely turns, makes an odd humming sound or overheats etc. then you will have to replace the condenser fan motor. This is assuming that the outdoor condenser has the 220v supplied and the 24v supplied to the compressor relay, that the compressor relay is engaged and suppling 220v to the condenser fan motor.
