Nordyne Intertherm 661017 Burner Orifice Natural Gas 17 Replacement for M1GH090 MGHA090

Product Description

The Nordyne Intertherm 661017 is a natural gas burner orifice designed as a direct replacement part for specific Intertherm furnace models. This orifice is a small but critical component in a gas furnace burner assembly. It controls the flow of natural gas into the burner, which directly affects combustion efficiency and flame quality. A properly sized and functioning orifice ensures that the right amount of gas reaches the burner at the correct pressure. This keeps the furnace running safely and at peak efficiency. HVAC technicians rely on exact-match replacement orifices to restore proper burner performance during service calls and repairs. Using an incorrect orifice size can lead to incomplete combustion, sooting, or unsafe operating conditions. The 661017 is confirmed to fit the Intertherm M1GH090 and MGHA090 furnace models, covering both 5-ton and 6-ton configurations in that product line. These are common residential and light commercial gas furnaces found throughout the field, making this a frequently needed service part. When diagnosing a furnace with uneven flames, a yellow or lifting flame, or signs of carbon buildup, the burner orifice is one of the first components to inspect and replace. This OEM-matched replacement from Nordyne Intertherm restores the correct gas metering for natural gas applications. It is not intended for use with propane or LP gas systems without proper conversion hardware. HVAC technicians, service contractors, and maintenance professionals working on Intertherm and Nordyne brand furnaces should keep this part on hand for efficient field repairs. Stocking the 661017 reduces downtime and ensures the correct part is available when needed.
