What MFD capacitor do I need for my Goodman AC?

The correct replacement for Goodman model SSX140601AB — CAP050700370RTS 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 Goodman equipment which lists the model number SSX140601AB — CAP050700370RTS.

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 Goodman 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 Goodman CAP050700370RTS is the OEM dual run capacitor for the SSX140601AB 14 SEER, 5-ton split-system air conditioner. Rated 70/5 MFD at 370V, it provides the starting and running torque for both the compressor (70 µF) and the condenser fan motor (5 µF) in a single round can. A failing capacitor is the most common cause of an outdoor unit that hums but won't start — this is a direct factory replacement.

Specifications

OEM Part Number: CAP050700370RTS
Fits: Goodman SSX140601AB (and compatible SSX14 series)
Capacitance: 70/5 MFD (µF) dual rated
Voltage: 370 VAC
Type: Dual run capacitor, round
Terminals: HERM / FAN / C quick-connect

OEM vs. Generic

The genuine OEM capacitor holds its rated microfarads and 370V tolerance under high outdoor heat, giving longer service life and reliable compressor starts. Generic capacitors often drift out of spec quickly, causing hard starts, motor overheating, and repeat failures. For a 5-ton compressor, OEM-grade reliability is strongly recommended.

Installation Difficulty

Easy to Moderate — disconnect power and discharge the old capacitor before removal, then transfer the leads to matching HERM/FAN/C terminals. Typically a 15–20 minute job. Warning: capacitors store a lethal charge — discharge fully before handling.

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.

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 Goodman 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 Goodman 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.
