What MFD capacitor do I need for my Tempstar AC?

The correct replacement for Tempstar model TCH936GKA200 — 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 TCH936GKA200 — 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 (Tempstar part number 1185068) is rated at 40 MFD and 440V and is the factory replacement for the Tempstar TCH936GKA200 condensing unit. The run capacitor delivers the phase-shifted current that lets the compressor or condenser fan motor start and run efficiently. As the capacitor degrades, it loses capacitance, forcing the motor to draw higher amperage, overheat, and struggle to start — and a failed capacitor will stop the motor entirely. Typical symptoms include a humming unit that will not start, a condenser fan that needs a manual push, hard starts, elevated amp draw, and a swollen or leaking capacitor can. A fresh 40 MFD capacitor restores rated performance and extends motor life.

Compatibility

Direct OEM fit for the Tempstar TCH936GKA200 and the equivalent ICP-built Heil and Comfortmaker condensing units that use a 40 MFD 440V run capacitor. Always verify the printed MFD and voltage rating on your existing capacitor before ordering.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, verify zero voltage with a multimeter, and discharge the capacitor with an insulated resistor.
Access — Remove the condensing unit service panel.
Document — Photograph all wire connections before disconnecting anything.
Remove — Note terminal markings, pull the spade connectors, and loosen the mounting strap to free the old capacitor.
Install — Mount the new 40 MFD 440V capacitor, secure the strap, and reconnect each lead exactly per your photo.
Test — Restore power and confirm the compressor and fan start cleanly at rated amperage.

Signs You Need a Replacement

Frequently Asked Questions

Does this Capacitor fit my Tempstar TCH936GKA200 — Single-Run | Ships Today?

Yes. This is the factory-specified OEM capacitor for the Tempstar TCH936GKA200 — 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 TCH936GKA200 — 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?
