What MFD capacitor do I need for my Tempstar AC?

The correct replacement for Tempstar model TCA960GKA100 — 370V Single Run | 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 TCA960GKA100 — 370V Single Run | 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 OEM single run capacitor (part number 1185070) provides the running torque for the compressor or motor in the Tempstar TCA960GKA100. Rated at 80 MFD and 370 volts, it stores and releases electrical energy to keep the motor windings running efficiently after startup. The run capacitor is one of the most failure-prone components in any condensing unit — heat, age, and voltage spikes cause it to lose capacitance or bulge and short. A weak or dead capacitor is the classic cause of a compressor that hums but won't start, a condenser fan that won't spin (or only spins when pushed), and high amp draw that trips breakers. Replacing it is a fast, inexpensive repair that restores full motor performance.

Specifications

Compatibility

A direct-fit OEM replacement for the Tempstar TCA960GKA100 condensing unit. The 1185070 80 MFD / 370V capacitor is shared across equivalent ICP-family equipment — Tempstar, Heil, Comfortmaker, Arcoaire, and ICP. A 370V capacitor may also replace a 440V unit of the same MFD, but never the reverse. Confirm the MFD value on your existing capacitor before ordering.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then discharge the capacitor across its terminals and verify zero voltage with a multimeter.
Access — Remove the condenser service panel to expose the capacitor.
Document — Photograph all terminal connections before disconnecting.
Remove — Pull the wire leads off the spade terminals and loosen the mounting strap.
Install — Secure the new capacitor in the strap and reconnect each lead to its matching terminal per your photo.
Test — Restore power and confirm the compressor and fan start cleanly.

Signs You Need a Replacement

Compressor or fan motor hums but will not start.
Condenser fan spins slowly or only when pushed by hand.
Bulged, leaking, or domed top on the capacitor case.
Measured capacitance far below the 80 MFD rating.

Frequently Asked Questions

Does this Capacitor fit my Tempstar TCA960GKA100 — 370V Single Run | Ships Today?

Yes. This is the factory-specified OEM capacitor for the Tempstar TCA960GKA100 — 370V Single Run | 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 TCA960GKA100 — 370V Single Run | 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.
