What MFD capacitor do I need for my Tempstar AC?

The correct replacement for Tempstar model TCH960GKA100 — 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 TCH960GKA100 — 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) delivers the steady phase-shifted current that keeps a motor running efficiently on your Tempstar TCH960GKA100. Rated at 80 MFD and 370 volts, it stores and releases energy to maintain torque on the connected motor or compressor. Capacitors are among the most failure-prone components in any HVAC system — heat and age cause them to lose capacitance, bulge, or short. A weak capacitor leads to hard starting, overheating, humming, and premature motor failure. Installing the correct 80 MFD / 370V OEM capacitor restores proper running torque.

Compatibility

Engineered for the Tempstar TCH960GKA100 and compatible with ICP-platform equipment from Tempstar, Heil, Comfortmaker, and Carrier specifying an 80 MFD, 370V single run capacitor. A 440V capacitor may safely replace a 370V unit, but always match the MFD rating exactly.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then discharge and verify zero voltage across the capacitor terminals with a multimeter.
Access — Remove the unit service panel to reach the capacitor bracket.
Document — Photograph the terminal wiring before disconnecting.
Remove — Slide the leads off the terminals and loosen the mounting strap.
Install — Secure the new capacitor in the strap and reconnect each lead to the matching terminal per your photo.
Test — Restore power and confirm the motor starts cleanly and runs without humming.

Signs You Need a Replacement

Motor hums but won't start, or starts slowly
Visibly bulged, leaking, or domed capacitor top
Capacitance reading well below 80 MFD on a meter
Frequent overheating or breaker trips on startup

How do I replace the capacitor on my Tempstar TCH960GKA100 — 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.

How fast does National HVAC Parts ship?
