What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model RGS240SEFA0AAAA — Blower Motor | 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 RGS240SEFA0AAAA — Blower Motor | 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 OEM run capacitor (part #1183001, listed as CAPACITOR PLATE) provides the continuous phase shift the blower motor needs to start and run smoothly on your ICP Tempstar Heil RGS240SEFA0AAAA gas furnace. Rated at 7.5 MFD and 370/440 volts, it stores and releases energy on every cycle to keep the indoor blower turning at the correct speed. A weak or failed capacitor is one of the most common furnace faults: as the capacitor loses capacitance the motor draws excess amperage, runs hot, hums without spinning, or short-cycles on thermal overload. Replacing a bulging or out-of-tolerance capacitor restores full airflow and protects the more expensive blower motor from premature burnout.

Compatibility

Designed as the factory replacement for the ICP Tempstar Heil RGS240SEFA0AAAA gas furnace and other RGS240-series units that share the same blower assembly. 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. Capacitors hold a charge — discharge it across a 20k-ohm resistor before handling.
Access — Remove the furnace blower compartment service panel.
Document — Photograph all wires before disconnecting.
Remove — Note the terminal positions, pull the spade connectors, and unclip the old capacitor from its mounting strap.
Install — Mount the new capacitor in the strap and reconnect each wire to the matching terminal per your photo.
Test — Restore power and confirm the blower starts promptly and runs at full speed without humming.

Signs You Need a Replacement

Blower motor hums but will not start spinning
Visibly bulged, leaking, or swollen capacitor top
Weak airflow or furnace short-cycling on overload
Measured capacitance reads outside the ±6% tolerance

Frequently Asked Questions

Does this Capacitor fit my ICP RGS240SEFA0AAAA — Blower Motor | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP RGS240SEFA0AAAA — Blower Motor | 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 RGS240SEFA0AAAA — Blower Motor | 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?

Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
