The INTERNATIONAL COMFORT PRODUCTS 1011626 is a low-voltage control transformer designed for residential HVAC and furnace applications. It steps primary voltage down from 115 volts to a 24-volt secondary output at a 40VA power rating, supplying the control circuit power that thermostats, contactors, and gas valve coils depend on. Rated for both 50Hz and 60Hz operation, this transformer meets OEM specifications for voltage output and thermal performance. Licensed HVAC technicians install this part during control circuit diagnostics, transformer failures, or full system replacements where original-spec components are required.
This transformer is suited for residential gas furnace and air handler control circuits where a reliable 24-volt low-voltage supply is essential. It is a direct OEM replacement built to original design specifications. Compatible models include NTG3100GFA4, NDN6100KFA2, and GNK100N16A3. It fits within standard transformer mounting locations found in typical forced-air furnace and air handler cabinets.
Compatible with the following models: NTG3100GFA4, NDN6100KFA2, and GNK100N16A3.
Installation should be performed by a licensed HVAC technician. Shut off all power to the furnace or air handler at the disconnect and breaker before removing the existing transformer. Verify primary and secondary voltage ratings match system requirements before energizing. Follow all applicable local electrical codes and manufacturer wiring diagrams during installation.
