What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model RHH048K0XA0AAAA — Round | 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 ICP equipment which lists the model number RHH048K0XA0AAAA — Round | 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.

Overview

This genuine OEM round dual run capacitor (part #1173702) is rated 45+10 MFD at 370 volts for the ICP RHH048K0XA0AAAA heat pump. A dual run capacitor provides the constant phase-shifted current that both the compressor (45 MFD side) and condenser fan motor (10 MFD side) need to run efficiently. As capacitors age, their microfarad value drifts low, leaving motors straining to start and run — the leading cause of hard starts, overheating, and tripped breakers in outdoor units. A bulged top or out-of-spec MFD reading means it's time to replace it.

Compatibility

Engineered for the ICP/Tempstar/Heil RHH048K0XA0AAAA and other ICP-family condensers and heat pumps specifying a 45+10 MFD 370V round dual run capacitor. A 370V capacitor may also be used in 440V applications; never substitute a lower voltage rating.

Installation Guide

Safety First — Disconnect power, verify zero voltage, and discharge the capacitor across its terminals with an insulated resistor.
Access — Remove the service panel to reach the capacitor.
Document — Photo the HERM, FAN, and C terminal wiring before disconnecting.
Remove — Loosen the mounting strap and pull the leads off the terminals.
Install — Mount the new capacitor and connect HERM, FAN, and C leads exactly per your photo.
Test — Restore power, call for cooling, and confirm the compressor and fan start promptly.

Signs You Need a Replacement

Bulged, leaking, or swollen capacitor top

Frequently Asked Questions

Does this Capacitor fit my ICP RHH048K0XA0AAAA — Round | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP RHH048K0XA0AAAA — Round | 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 ICP RHH048K0XA0AAAA — Round | 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 ICP 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 ICP 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?
