Nordyne Intertherm 621882 Power Choke Inductor

Product Description

The NORDYNE INTERTHERM 621882 is a power choke inductor used in the control circuitry of residential and light commercial HVAC systems. Also referenced as Tyco 6673, this component is an inductor/coil assembly designed to regulate electrical current and suppress high-frequency noise on control boards. It helps maintain stable voltage conditions across the control circuit, protecting downstream components from electrical interference. Licensed HVAC technicians performing control board service or board-level component replacement are the primary installers of this part.

This power choke is used in heating and cooling systems where control board stability is critical. It is found in gas furnaces, electric furnaces, heat pumps, and air handlers that use low-voltage control boards. The part serves as an OEM-style replacement within Nordyne, Miller, Intertherm, Frigidaire, and Maytag branded HVAC equipment lines. It fits applications where the original control board design incorporated a power choke for current regulation and noise filtering in the control circuit.

Key Features

• Inductor/coil design regulates current flow and filters electrical noise on HVAC control boards
• Also referenced as Tyco 6673 for cross-reference sourcing
• Magnetic core with coil winding construction standard for HVAC control applications
• Direct OEM-style replacement for control boards in Nordyne-platform equipment
• Supports stable control board operation and reduces risk of noise-induced component failure

Compatibility

Compatible with HVAC units manufactured by Nordyne, Miller, Intertherm, Frigidaire, and Maytag. Also cross-references Tyco part number 6673.

Installation Notes

Installation should be performed by a licensed HVAC technician with experience in control board component service. Disconnect all power to the unit at the disconnect switch and confirm zero voltage before handling any control board components. Proper handling procedures for static-sensitive components should be observed during removal and installation. Work should comply with applicable local electrical codes and the equipment manufacturer service documentation.
