What MFD capacitor do I need for my Tempstar AC?

The correct replacement for Tempstar model TCA760GKB101 — OEM 1185266 | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Tempstar equipment which lists the model number TCA760GKB101 — OEM 1185266 | Ships Today.

My AC hums but will not start. What part do I need?

An AC that hums but will not start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost needed to start the compressor and fan motors. When it fails, you hear the hum of the motor trying to start but it cannot overcome inertia. Other symptoms include the fan spinning slowly, the AC cycling on and off rapidly, or a visibly swollen or leaking capacitor. Replacement cost: $15 to $80 for the part, DIY in 30 minutes.

Is this capacitor compatible with Bryant or Payne systems too?

Many Tempstar parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

Overview

This is a genuine OEM dual run capacitor (part number 1185266) for the Tempstar TCA760GKB101 condensing unit. Rated at 40+7.5 MFD and 440 volts, the dual run capacitor provides the phase shift needed to start and run both the compressor (40 MFD side) and the condenser fan motor (7.5 MFD side) from a single component. When the capacitor weakens or fails, the system loses the torque required to spin its motors. Common failure symptoms include a humming compressor that won't start, a condenser fan that needs a manual push to begin turning, intermittent hard-starting, breaker trips, and a unit that blows warm air on a cooling call. Capacitors degrade over time from heat and electrical stress, so a bulging top, leaking oil, or a reading outside the rated microfarad range confirms replacement is needed.

Specifications

Type	Dual Run Capacitor
Brand	Tempstar
Capacitance	40 + 7.5 MFD
Voltage	440V (compatible with 370V applications)

Compatibility

Engineered as the direct OEM replacement for the Tempstar TCA760GKB101 air conditioning condenser. The 440V rating also safely covers original 370V capacitor positions. Always confirm the MFD values and terminal labeling on your existing capacitor before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter. Discharge the old capacitor across its terminals with an insulated screwdriver before touching it.
Access — Remove the condenser service panel to expose the electrical compartment.
Document — Photograph all wire connections (HERM, FAN, C) before disconnecting anything.
Remove — Note each wire's terminal, pull the spade connectors, and unfasten the capacitor mounting strap.
Install — Secure the new capacitor in the strap and reconnect each wire to its matching terminal per your photo.
Test — Restore power and confirm the compressor and condenser fan start promptly and run smoothly.

Signs You Need a Replacement

Compressor hums but won't start, or trips the breaker
Condenser fan won't spin until pushed by hand
Bulging, swollen, or leaking capacitor case
MFD reading falls outside the rated 40+7.5 range

How do I replace the capacitor on my Tempstar TCA760GKB101 — OEM 1185266 | Ships Today?

Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.

My AC hums but won’t start. What part do I need?

An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).

Is this capacitor compatible with Bryant or Payne too?

Many Tempstar parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my Tempstar capacitor?

OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.

How fast does National HVAC Parts ship?
