I have a carrier package unit 50HJQ005-631 SERIAL 160BG50314, condenser fan motor wont come on, we found motor was gone and we replaced, capacitor too is new, but still dont come on.we test the contactor...

are you getting power to contactor? 240 volts. is the thermostat calling to the contactor you should have 24 volts to the contactor from the thermostat to turn it on the out side unit. check to see if the contactor is suck in this is in the middle of the contactor you can push it in to see if you are getting power if you push it in then youa re not calling from thremostat.

Panasonic th-50px75u no power

Ensure there is proper voltage on the power outlet. Try changing the TV to a different power outlet you are sure that works. Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

I need to know how to wire up a 4 wire motor to two capacitors. Also, i have a 45 MFD 440 VAC and a 5x370 i need to which one is for the compressor and which one is for the fan?

Each motor, compressor have there own capacitor, The 45uf is for the compressor and the 5uf is for the fan motor. If the motor has two brown wires and a black wire, white/or yellow wire the brown wires go to the capacitor and the other two go to the contactor for power. Black to common side of contactor (black)and the other to the red/or yellow side of contactor.

I get power to motor but it does not turn on had the motor check it is ok, replaced the pressure regulator and still nothing

If you are getting power to the motor it should hum run or make some noise. If no noise suspect contactor coil if equiped with one. Does this unit have a starter on it. If so the contactor coil is probably bad. you will have to remove the contactor from the starter box and disassemble the contactor to remove the coil. Depending on what type contactor it is you may be able to obtain a coil at the local electrical supply house. Of course if your luck is like mine you will need to obtain the coil from the manufacture. Also does this unit have a low oil level switch. If so make sure you have enought oil in it.Really need to know manfacture and model. one other possibility is the pressure switch. It could be stuck in the open position.

Sounds like unit is getting power but fan doesnt come on

Confirm with a volt meter that you are getting the required voltage from the condenser fan motor contactor, load side of the contactor,which should be the same contactor as for the compressor. Is the comprssor coming on. If the compresor is coming on and the fan motor is'nt, than the fan motor or the run capcitor for the fan motor has failed.

I have a Th-46pz85u panasonic plasma tv that is blinking the power light 10 times. I was curious to see what the replacement part is to fix that problem. I have the Panasonic error codes and that error...

Yes,this codes is a 100% correct is ur power supply board.U searches all around the power supply board and it supporting boards for those leakages gases capacitors?These capacitors alway have bulges on it top or puff on it top.Replaced these bad capacitors,u will get ur power voltages stable and ur power supply board will work.Not,than one or more of ur power transformers have a shorted power pins legs.The power transformers,coil is dead.The transformer must be replaced.

Why do you want to run the motor in the delta configuration? The VFD will change the speed to anything you want to do. The delta and Wye connections are normally used to change the speed of a motor. That's what the VFD is for...??

No heat , out door unit doesn't run?

turn fan switch at stat to on . does fan run? it should within 2 to 3 minutes if not sooner. if it does then you know you have low voltage and high voltage a blower and electronic brain . go outside and see of you hear a hum like a faint buzz. that is the contactor being closed and energized. check to see if outdoor disconnect has power ,usually 220 volts and then remove service panel and see if 220 volts arrives at contactor. see if spring loaded contactor points are pulled in and check to see if voltage is feeding through contactor . this will be hot! be sure you know how to use a meter and work live power. if contactor is not pulled in then you have a control voltage problem and you have to get 24 volts from stat to indoor blower to outdoor condensor. with and insulated screwdriver you can simply mash in on the contactor points and fan and compressor should run . only do this for a second or two, but it does simply say hey contactors open, ive got power and it will run but no controll volytage.IF ITS A RUUD OR A RHEEM SOME OF THEM HAVE A RESET BUTTON DOWN WHERE THE REF LINES GO IN . MASH IT IN AND IT MAY RESET, THEYTRIP OFF HIGH PRESSURE, DIRTY FILTER OR COIL IN HEAT OR A BAD FAN MOTOR OUTSIDE IN COOL.
