OEM Carrier ERV Motor Capacitor with Pulley for Model EMSH4BG — Part #62M680306

This is the factory OEM replacement ERV (Energy Recovery Ventilator) motor capacitor with pulley assembly for the Carrier EMSH4BG unit. The run capacitor provides the phase-shifted electrical charge required to start and continuously run the ERV blower motor. When this capacitor degrades or fails, the ERV motor may hum without spinning, fail to start entirely, or draw excess current leading to motor burnout. Replacing this capacitor promptly protects the motor from secondary damage and restores proper ventilation performance.

  • Specs: Factory-matched MFD and voltage rating for Carrier EMSH4BG ERV motor | Includes pulley assembly | OEM part number 62M680306 | Meets factory tolerance specifications for reliable motor starting and runtime
  • OEM vs Generic: This is a genuine Carrier OEM component engineered to exact factory specifications. Aftermarket capacitors often carry wider MFD tolerances (±10% or more), which can accelerate motor winding wear and shorten the service life of the ERV motor assembly.
  • Install difficulty: 3/5 — Always disconnect power and discharge the capacitor before handling. The included pulley requires proper belt alignment on reassembly. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter for capacitance verification, and a belt tension gauge. Photograph all wiring and belt routing prior to disassembly.
  • Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed specifically for the Carrier EMSH4BG Energy Recovery Ventilator. Always verify the part number 62M680306 against your unit's data plate and wiring diagram before ordering. Our technical team is available to confirm fitment — reach out before you buy if you have any questions. Order today and receive same-day shipping on all in-stock parts.

Frequently Asked Questions

Does this Capacitor fit my Carrier EMSH4BG — 62M680306?
Yes. This is the factory-specified OEM capacitor for the Carrier EMSH4BG — 62M680306. 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 Carrier EMSH4BG — 62M680306?
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 Carrier 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 Carrier 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.
