What MFD capacitor do I need for my Tempstar AC?

The correct replacement for Tempstar model TCA960GKA200 — 40 MFD 440V | 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 TCA960GKA200 — 40 MFD 440V | 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 genuine OEM single run capacitor (part number 1185068) is rated 40 MFD at 440 volts for the Tempstar TCA960GKA200 air conditioner. A run capacitor stores and releases electrical energy to give the compressor or fan motor the continuous phase shift it needs to run smoothly and efficiently. As capacitors age they lose capacitance, swell, or short out — the leading cause of a unit that hums but won't start, trips the breaker, or runs hot. Replacing a weak capacitor restores proper torque and protects the motor from premature failure. This 440V-rated unit is also suitable for 370V applications.

Compatibility

Direct-fit OEM replacement for the Tempstar TCA960GKA200 and shared across many ICP-family (Tempstar, Heil, Comfortmaker) condensing units that call for a 40 MFD, 440V single run capacitor. Confirm the microfarad and voltage rating against your existing capacitor before ordering.

Installation Guide

Safety First — Disconnect power at the 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 reach the capacitor.
Document — Photograph the terminal wiring before disconnecting.
Remove — Disconnect the leads, loosen the mounting strap, and lift out the old capacitor.
Install — Mount the new capacitor, secure the strap, and reconnect each lead per your photo.
Test — Restore power and command cooling to confirm the fan and compressor start cleanly.

Signs You Need a Replacement

Unit hums but the fan or compressor won't start.
Bulging, leaking, or domed top on the capacitor case.
Capacitance reads well below the rated 40 MFD on a meter.
Frequent breaker trips or a condenser that starts then stalls.

Frequently Asked Questions

Does this Capacitor fit my Tempstar TCA960GKA200 — 40 MFD 440V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the Tempstar TCA960GKA200 — 40 MFD 440V | 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 TCA960GKA200 — 40 MFD 440V | 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?
