What MFD capacitor do I need for my Tempstar AC?

The correct replacement for Tempstar model TCA924GKA100 — 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 TCA924GKA100 — 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 1185067) provides the steady phase shift that keeps the compressor or condenser fan motor turning efficiently on your Tempstar TCA924GKA100. Rated 35 MFD at 440V, it stores and releases the energy the motor needs to run smoothly under load. A failing capacitor is the single most common HVAC service call — symptoms include a humming unit that won't start, a fan that needs a push to spin, hard starting, high amp draw, and a bulged or leaking capacitor top. Installing the correct 35 MFD / 440V OEM part restores full starting torque and protects the motor windings from overheating.

Compatibility

Built for the Tempstar TCA924GKA100 and the ICP / Heil / Comfortmaker condensing units that share this 35 MFD 440V run capacitor. A 440V capacitor can safely replace a 370V unit of the same MFD, but the MFD value must match exactly.

Installation Guide

Safety First — Disconnect power and verify zero voltage, then discharge the capacitor across its terminals with an insulated resistor before touching it.
Access — Remove the service panel on the condensing unit.
Document — Photograph all terminal wiring before disconnecting.
Remove — Note the terminal markings, disconnect the leads, and release the mounting strap.
Install — Secure the new capacitor and reconnect each lead to its matching terminal per your photo.
Test — Restore power and confirm the motor starts instantly and runs without humming.

Signs You Need a Replacement

Motor hums but won't start, or needs a manual push to spin

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.
