What MFD capacitor do I need for my Tempstar AC?

The correct replacement for Tempstar model TCH936GKA100 | 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 TCH936GKA100 | 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

The Tempstar OEM run capacitor (part #1185068) is a 40 MFD, 440-volt single-run motor capacitor for the TCH936GKA100 condensing unit. A run capacitor stores and releases electrical energy to give the compressor or condenser fan motor the steady phase shift it needs to run efficiently. As capacitors age they lose capacitance or fail outright, leaving the motor unable to start or causing it to run hot and draw excess current. Telltale symptoms include a compressor or fan that hums but won't spin, a fan that needs a push to start, frequent breaker trips, or a swollen/leaking capacitor top.

Specifications

Type	Single-Run Capacitor
Brand	Tempstar (ICP / Heil)
Capacitance	40 MFD (µF)
Voltage Rating	440 VAC

Compatibility

This capacitor is the factory-specified replacement for the Tempstar TCH936GKA100 and works in compatible ICP, Heil, and Comfortmaker units calling for a 40 MFD 440V run capacitor. A 440V-rated capacitor can safely replace a 370V unit of the same MFD, but never substitute a different capacitance. Confirm the MFD value against your original or the unit data plate.

Installation Guide

Safety First — Disconnect power, verify zero voltage with a multimeter, and discharge the old capacitor across its terminals before handling.
Access — Remove the condenser electrical access panel.
Document — Photograph the terminal wiring before disconnecting.
Remove — Note which leads land on each terminal, disconnect them, 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 immediately and runs smoothly.

Signs You Need a Replacement

Frequently Asked Questions

Does this Capacitor fit my Tempstar TCH936GKA100 | Ships Today?

Yes. This is the factory-specified OEM capacitor for the Tempstar TCH936GKA100 | 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 TCH936GKA100 | 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?
