What MFD capacitor do I need for my Tempstar AC?

The correct replacement for Tempstar model TCH660GKA200 — 40+7.5 MFD 440V | 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 TCH660GKA200 — 40+7.5 MFD 440V | 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 genuine OEM dual run capacitor (part number 1185266) serves both the compressor and the condenser fan motor on the Tempstar TCH660GKA200 heat pump. Rated at 40 + 7.5 MFD and 440 volts, the 40 MFD side supports the compressor while the 7.5 MFD side runs the outdoor fan — two capacitors in one can. A dual run capacitor provides the continuous phase shift that keeps both motors turning efficiently and at the correct amp draw. When one side weakens, you may see the fan spin but the compressor hum and stall, or vice versa. A bulged or failed dual capacitor is one of the most common causes of a no-cooling call, and it is a fast, low-cost fix that restores full system output.

Compatibility

Engineered as the factory replacement for the Tempstar TCH660GKA200 heat pump. This 40+7.5 MFD / 440V dual run capacitor is a common service part across ICP-family units sold under the Heil, Comfortmaker, and Tempstar brands that specify these ratings. Match both MFD values and the voltage to your original before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker. Verify zero voltage with a multimeter, then discharge the old capacitor across its terminals with an insulated screwdriver.
Access — Remove the condenser service panel to expose the capacitor.
Document — Photograph the HERM, FAN, and C terminal wiring before disconnecting.
Remove — Pull the spade connectors and unclip the mounting strap holding the capacitor.
Install — Mount the new dual capacitor and reconnect each wire to its matching HERM, FAN, and C terminal per your photo.
Test — Restore power, start cooling, and confirm both the compressor and fan start immediately at normal amps.

Signs You Need a Replacement

Fan runs but the compressor hums and won't start (or the reverse).
Bulged, domed, or leaking capacitor top.
System trips the breaker or short-cycles on startup.
Measured capacitance on either side is more than 6% off rating.

How do I replace the capacitor on my Tempstar TCH660GKA200 — 40+7.5 MFD 440V | 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.
