Dayton Motor and capacitors for Carrier AC Unit (model # 38ck030300)

I purchased a Dayton Motor (4M205G), and a Dayton capacitor (MPP2505370J) and I need to confirm the proper wiring setup to the capacitors and contactor. I have a 1.5 pole 30 amp 24VAC Definite purpose contactor from Mars.

Currently my compressor will not start, but I think I have something miswired.

The 2 brown wires to the cap in first legend is how they are wired electrically,inside that motor the run winding is common to that brown one they cappped off in the 2nd option, but the powers still going to Run.ommon and run get the juice either way, its just another way to do it, but electrically as to sides of power and where they go is no different, just different way to do it.you can run power in on the Run terminal on the run cap, the run winding and run cap and start cap if equipped are Run to Run to Run.So the hot leg for the run winding also goes to run on the caps, run to run to run.,run winding to run cap to run on start cap.

I don't know what part of the country you are in, but here in Okla. a condenser motor can be bought by the home owner for around $100. You should be able to go to any appliance supply house and purchase your own motor. Take the model and serial number with you, it may help. If you have a local carrier distributor, they should give you a users manual. Try your best to get a motor close the the same as what you have. Note the horsepower, rpm, voltage and take the fan blade with you in case you need a new one. Hope this helps. Mark

Fan is getting power but will not spin..can hear it hummin, motor is dayton model 2LY98


Most of the time if there is power to the motor and all it does is 'hum' then you have a bad motor.
Before replacing it however - I would look at it's capacitor (a small device, usually silver in color, about he size of a pack of cigerettes) and see if it's visibly 'bulged' which is most always an indication that it's bad. If it is - you could solve your problem by changing the capacitor. Also, you could check for electrical connections that have burnt off or have come loose. There is just a slight chance that the capacitor/wiring is your problem - but it's worth checking out. If not, then you will need to get an AC tech to troubleshoot the system, unless you decide to just replace the motor yourself.
Note: If this is a 'central unit' with an 'outside unit' and all it does is 'hum' there is slight chance that what you are hearing is the 24V causing the contactor (in the unit) to hum which is pretty much normal - however - if this the problem and the outside unit is not running (only humming) I would check my fuses and breaker. You could just have a blown fuse or a breaker that needs resetting.
ALWAYS make sure the electrical power is completely OFF before trying to make any checks/repairs.
Hope this helps.

Look at the old capacitor. The mircofarad rating should be printed on the side. If you can't read it then take the capacitor or the model # with you to a heating and air dealer the sells Carrier products. The repairman should have put one it for you.

Do no what wires go where on the capacitor for our carrier a/c unit


Some capacitor start motors have two brown leads (one with white stripe) that go to capacitor. Others wire into the start winding, if that is the case follow wiring diagram on the motor. Also if this is in an A/C unit follow the wiring diagram in the unit (usually on inside of cover)

The condenser fan for carrier xarios 300 is not


there is a run capacitor is probably bad.
you can purchase a replacement one from slakey brothers. However the capacitor will still have a charge after the power and wires are removed. after turning off the breaker use a long bladed screw driver and ground the electrical leads to discharge the capacitor before removing. take it with you to the supply house along with the model and serial number of the condensing unit.
