Replaces / Cross-Reference Part Numbers

This component is a direct replacement for any start capacitor with matching capacitance, voltage, and frequency specifications. It is a suitable alternative for parts including, but not limited to:

  • Titan Pro TRMJ88

Compatibility & Fitment

Designed for use in single-phase AC electric motors. Common applications include:

  • Air conditioners
  • Heat pumps
  • Compressors
  • Refrigeration units
  • Well pumps and other electric motors

When to Replace

A failing start capacitor can cause motor issues. Consider replacement if you observe the following symptoms:

  • Motor hums but does not start or struggles to start
  • Motor cycles off on thermal overload protector
  • No motor function
  • Visible signs of damage to the capacitor, such as bulging, cracking, or leaking fluid

Installation Tips

  • Safety First: Disconnect all electrical power to the unit before servicing.
  • Discharge Old Capacitor: Safely discharge the existing capacitor using a properly rated resistor to avoid electrical shock.
  • Verify Specifications: Ensure the capacitance (µF/MFD) and voltage (VAC) ratings of the new capacitor match the original part. The voltage rating can be equal to or higher than the original, but never lower.
  • Note Connections: Take a photo or make a note of the wire connections before removing the old capacitor to ensure correct reassembly.
  • Secure Mounting: Mount the new capacitor securely using the existing bracket or strap.

FAQ

Common symptoms of a failing start capacitor include the motor humming or buzzing without turning, the motor struggling to reach full speed, or the motor failing to start entirely. If the capacitor casing is bulging, leaking, or shows signs of burn marks, it should be replaced immediately.
Yes, this capacitor is a universal replacement for units rated 88-108 MFD at 330 VAC. It is compatible with various industry part numbers, including CON-88-330, 092A088B330BD4A, TRMJ88, and PRMJ88.
The MFD (microfarad) rating must match the range specified by your motor manufacturer to ensure the correct amount of torque is provided during startup. The VAC (voltage) rating indicates the maximum voltage the capacitor can handle; you can safely use a capacitor with a higher voltage rating than the original, but never one with a lower rating.
Before installation, always disconnect the power supply to the equipment. Use an insulated screwdriver to short the terminals of the old capacitor to discharge any stored energy safely. Additionally, inspect the motor's centrifugal switch; if the switch is stuck or faulty, it can cause the new capacitor to fail prematurely.
Motor start capacitors are designed for intermittent use to provide a boost during startup. Their lifespan is heavily influenced by the number of starts and the operating temperature. Frequent cycling, high-heat environments, or voltage spikes can shorten their service life significantly.
