What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model RGS240HTEA0AAAA — 5 MFD 370V | 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 RGS240HTEA0AAAA — 5 MFD 370V | 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 is the genuine OEM run capacitor (part 1183001) for the ICP / Heil / Tempstar RGS240HTEA0AAAA gas furnace. Rated at 5 MFD / 370V, it provides the steady phase-shifted current the blower motor needs to maintain torque and run efficiently. A run capacitor stores and releases energy on each cycle, keeping the motor turning smoothly under load. When it weakens or fails, the blower motor struggles to start, runs hot, hums without spinning, or cycles on its internal overload. A failed capacitor is one of the most common and inexpensive causes of a no-airflow furnace call, and a quick check with a capacitance meter confirms whether the reading has drifted below its rated MFD value.

Compatibility

Direct-fit replacement for the ICP RGS240HTEA0AAAA gas furnace and related Heil, Tempstar, and Comfortmaker platform models using the same 5 MFD 370V blower capacitor. Verify the MFD and voltage printed on your existing capacitor before installing.

Installation Guide

Safety First — Disconnect power at the switch and breaker, then verify zero voltage with a multimeter.
Access — Remove the blower compartment service panel.
Document — Photograph the capacitor terminals and wire colors before disconnecting.
Remove — Safely discharge the old capacitor across its terminals with an insulated resistor, then pull the leads and release the mounting strap.
Install — Secure the new capacitor and reconnect each lead to the matching terminal per your photo.
Test — Restore power and confirm the blower starts immediately and runs smoothly.

Signs You Need a Replacement

Blower motor hums but will not start spinning

Frequently Asked Questions

Does this Capacitor fit my ICP RGS240HTEA0AAAA — 5 MFD 370V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP RGS240HTEA0AAAA — 5 MFD 370V | 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 RGS240HTEA0AAAA — 5 MFD 370V | 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?
