Service your WeatherKing 13AJA36A01 central air conditioner with genuine OEM replacement parts from Repair Clinic. The WeatherKing 13AJA36A01 is a 3-ton 13-SEER single-stage cooling-only condensing unit. WeatherKing is a brand in the ICP (International Comfort Products) family, which also includes Heil, Tempstar, and Arcoaire; all of these brands share the same manufacturing platform and use identical components at the same configuration. The serial prefix 7655 in the 13AJA36A01/Serial: 7655 designation identifies the production date range and does not affect parts compatibility for capacitors, contactors, fan motors, or fan blades. Parts most frequently replaced on this unit include the run capacitor, contactor, condenser fan motor, and control board. Use the 13AJA36A01/Serial: 7655 parts list to confirm your component, then browse the full ICP central air conditioner parts catalog.
WeatherKing 13AJA36A01 on the ICP Platform: Brand Family and 3-Ton Output Class Context
The WeatherKing 13AJA36A01 is manufactured by International Comfort Products on the same platform shared by Heil, Tempstar, and Arcoaire. Parts sourced under any of these brand designations at the same configuration are identical; if a 13AJA36A01 component search returns no result under the WeatherKing designation, searching under Heil or Tempstar at the same model number pattern will return compatible components. The 13AJA36A01 designation encodes the series (13AJA), the 036 tonnage class indicating 3-ton (36,000 BTU) capacity, and the production revision. The 3-ton output class determines the fan motor and condenser coil specifications; motors and blades from 2-ton or 4-ton ICP configurations within the same platform generation are not valid substitutes for the 13AJA36A01 motor and blade.

13AJA36A01 Service Items and Failure Patterns at the 3-Ton Class
13AJA36A01/Serial: 7655 Capacitor Annual Testing and Compressor Protection
The run capacitor on the WeatherKing 13AJA36A01/Serial: 7655 Air Conditioner is a dual-run unit serving the compressor and condenser fan motor. Capacitor dielectric degradation is a cumulative process driven by thermal cycling; a capacitor that was at the lower edge of its specification range when new may drift out of specification after two to three cooling seasons rather than the typical four to five. Annual microfarad testing at cooling season start identifies drift before mid-season failure. Replace the capacitor if either the compressor or fan motor section reads more than five percent below the rated value on the label. Find the correct replacement at the ICP central air conditioner capacitor page.
Condenser Fan Motor Seizure Risk on the WeatherKing 13AJA36A01
The 13AJA36A01/Serial: 7655 motor drives the condenser fan that rejects heat from the refrigerant during every cooling cycle. Bearing wear in the motor produces a grinding or squealing noise that progresses to motor seizure, at which point the compressor overheats within minutes without the fan moving air across the coil. A unit that produces unusual bearing noise from the outdoor cabinet should have the fan motor replaced before the bearing seizes, because sustained high-discharge-pressure operation from a seized fan motor can damage the compressor in a single extended cooling cycle on a hot day. Browse ICP central air conditioner fan motor parts for the correct 3-ton replacement.
WeatherKing 13AJA36A01 Control Board and Sequence Fault Diagnosis
The control board on the WeatherKing 13AJA36A01 manages the unit’s operational sequence, safety input monitoring, and thermostat communication. A board fault presents as a unit that receives a thermostat cooling call but does not engage the contactor, a compressor that starts without the condenser fan following, or a unit that does not respond to the thermostat call at all. Before condemning the control board, verify 24-volt control circuit voltage at the board input terminals and confirm the thermostat is sending a valid cooling call; a failed 24-volt transformer or broken thermostat wire produces the same symptoms at lower replacement cost. Browse ICP central air conditioner control board parts.
Contactor Contact Inspection on the 13AJA36A01 at 3-Ton Switching Load
The contactor on the 13AJA36A01/Serial: 7655 Air Conditioner switches line voltage to the 3-ton compressor and condenser fan motor at every thermostat cycle. At 3-ton output, the contactor handles higher switching loads than at 2-ton, accelerating contact face erosion proportionally. Inspect the contact face surfaces at each annual cooling season service; replace the contactor when visible pitting, blackening, or face erosion is present, and replace proactively every five years regardless of visual condition in warm climates where the unit operates for extended seasons. Find compatible parts at the ICP air conditioner contactor page.

WeatherKing 13AJA36A01 Air Conditioner Parts FAQ
What brands are interchangeable with the WeatherKing 13AJA36A01?
WeatherKing is part of the ICP (International Comfort Products) family, which includes Heil, Tempstar, and Arcoaire. All of these brands share the same manufacturing platform and use identical components at the same configuration. Parts ordered for the 13AJA36A01 under any of these brand designations are interchangeable with no modification required.
What does the Serial: 7655 designation mean for 13AJA36A01 parts ordering?
The 7655 serial prefix identifies the production week and year of manufacture. For run capacitors, contactors, fan motors, and fan blades, this serial date has no impact on parts compatibility within the 13AJA36A01 model. For control boards and wiring harnesses, confirm the serial range is covered in the specific listing before ordering.
Why is my WeatherKing 13AJA36A01 running but not cooling effectively?
Reduced cooling with the unit running is most commonly caused by a degraded run capacitor reducing compressor and fan motor efficiency, a pitted contactor dropping supply voltage to the compressor, a condenser coil restricted by debris reducing heat rejection, or a fan motor running below rated RPM due to bearing wear. Test the capacitor first, then inspect the contactor, then clean the condenser coil before considering refrigerant charge as the cause.
Can I use a Heil or Tempstar fan motor in my WeatherKing 13AJA36A01?
Yes. The 13AJA36A01 fan motor and all other service components are identical across the WeatherKing, Heil, Tempstar, and Arcoaire brand designations at the same 3-ton configuration. Parts ordered under any ICP brand designation at the same output class fit the 13AJA36A01 correctly with no modification.
