Nordyne 903106a Integrated Control Assembly Utec

Product Description

The NORDYNE 903106a is an integrated control assembly built around a Universal Thermostat Equipment Controller (UTEC) platform. This board serves as the central control module for a gas furnace, managing ignition sequencing, blower motor timing, and safety circuit monitoring in a single consolidated unit. Licensed HVAC technicians install this part when diagnosing a failed or non-responsive control board that is causing lockout faults, ignition failures, or erratic blower behavior. The UTEC architecture consolidates functions that older multi-board systems handled separately, reducing component count and simplifying diagnostics during service calls.

This integrated control assembly is intended for residential gas furnace applications where the original Nortek-supplied UTEC board has failed or been damaged. It fits into the furnace control compartment and interfaces with the gas valve, pressure switches, limit switches, igniter, and low-voltage thermostat wiring. HVAC technicians working on Nortek-platform furnaces will encounter this board as an OEM-style replacement in single-stage heating configurations.

Key Features

• UTEC integrated architecture consolidates ignition control, blower sequencing, and safety monitoring on a single board
• OEM-style replacement designed to match original mounting and wiring configuration
• Interfaces with gas valve, pressure switches, limit switches, and thermostat low-voltage circuit
• Designed for residential gas furnace applications on Nortek-platform equipment
• Sold as an individual unit (each)

Compatibility

Designed as an OEM-style replacement for residential gas furnace integrated control boards on Nortek-platform equipment. This part carries manufacturer part number 903106 as the base reference. Confirm fitment against the original board part number before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable local mechanical codes and manufacturer service instructions. Shut off all electrical power to the furnace at the disconnect switch and set the gas valve to the off position before removing the existing control board. Photograph all existing wiring connections before disconnecting them to ensure correct reconnection. After installation, verify proper ignition sequencing and safety circuit operation before returning the system to service.
