What MFD capacitor do I need for my Tempstar AC?

The correct replacement for Tempstar model TCA936GKA200 — 40/440 | 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 TCA936GKA200 — 40/440 | 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 single-run capacitor (part number 1185068) rated at 40 MFD and 440V for the Tempstar TCA936GKA200 condensing unit. The run capacitor delivers the phase-shifted current the compressor and condenser fan motor need to start and run efficiently. As capacitors age they lose capacitance, which leads to hard starting, breaker trips, overheating motors, and short-cycling on hot days. Swapping in a fresh 40 MFD capacitor restores proper starting torque and protects the compressor from premature failure. The 440V rating gives generous headroom over the unit's 208/230V supply for dependable, long-lasting service.

Compatibility

Engineered for the Tempstar TCA936GKA200 condenser and shared across many ICP-family units (Heil, Comfortmaker, Arcoaire) built on the same platform. Always confirm the MFD and voltage rating against your existing capacitor before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and verify zero voltage with a multimeter. Capacitors store a charge.
Access — Remove the condenser electrical access panel.
Document — Photo all wires before disconnecting.
Discharge & Remove — Safely discharge the old capacitor across the terminals with an insulated resistor, then disconnect the leads and release the mounting strap.
Install — Mount the new 40 MFD capacitor, secure the strap, and reconnect each terminal per your photo.
Test — Restore power and verify the compressor and fan start and run normally.

Signs You Need a Replacement

Outdoor unit hums but the fan or compressor will not start.
Capacitor top is bulged, leaking, or domed.
System short-cycles or trips the breaker on startup.
Measured capacitance reads well below 40 MFD.

Frequently Asked Questions

Does this Capacitor fit my Tempstar TCA936GKA200 — 40/440 | Ships Today?

Yes. This is the factory-specified OEM capacitor for the Tempstar TCA936GKA200 — 40/440 | Ships Today. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the capacitor on my Tempstar TCA936GKA200 — 40/440 | 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?
