What MFD capacitor do I need for my Tempstar AC?

The correct replacement for Tempstar model T9UHX100L20A1 — OEM 1014315 | 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 T9UHX100L20A1 — OEM 1014315 | 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 oval run capacitor (Tempstar part #1014315) provides the continuous phase-shift current that keeps the blower motor in your Tempstar T9UHX100L20A1 gas furnace spinning smoothly. A run capacitor stores and releases energy to maintain proper torque and efficiency on the motor windings. When it weakens, you'll see a motor that hums but won't start, a blower that runs hot, intermittent operation, or a furnace that trips on a motor overload. This is a single-run oval capacitor rated at 7.5 MFD and 370/440V — the dual voltage rating means it drops into systems calling for either value.

Compatibility

Engineered for the Tempstar T9UHX100L20A1 9-series gas furnace and shared across many Heil, ICP, and Comfortmaker furnace platforms using OEM capacitor 1014315. Always confirm the MFD and voltage stamped on your existing capacitor before installing.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter. Discharge the old capacitor across its terminals with an insulated resistor.
Access — Remove the blower compartment service panel.
Document — Photograph all wire connections and terminal markings before disconnecting anything.
Remove — Note lead positions, pull the spade connectors, and loosen the mounting strap to free the old oval capacitor.
Install — Seat the new capacitor in the strap, reconnect leads exactly per your photo, and tighten the mount.
Test — Restore power and confirm the blower starts promptly and runs steadily without humming or overheating.

Signs You Need a Replacement

Blower motor hums but won't start spinning

How do I replace the capacitor on my Tempstar T9UHX100L20A1 — OEM 1014315 | 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.
