Tappan furnaces are built tough, but when they fail, you need the right OEM parts fast. Whether your Tappan gas furnace won't ignite, won't heat, or trips the pressure switch constantly, we carry the exact parts that restore it to full operation.
The most common Tappan furnace repairs involve hot surface igniters, draft inducer motors, pressure switches, and flame sensors. These parts are inexpensive compared to a service call, and many are DIY-friendly. Verify your model number on the furnace nameplate to ensure exact compatibility — Tappan is part of the Nordyne family, and model variations matter.
The hot surface igniter is the #1 Tappan furnace failure. When the igniter glows orange but the gas valve won't open, or it doesn't glow at all, you've found your culprit. It's a $30 to $60 OEM part and a straightforward 20-minute replacement. Silicon carbide igniters are the standard type for most Tappan models, but verify yours before ordering — some older units use different types.
The model number is stamped on the rating nameplate, which is usually mounted on the side or front of the furnace cabinet. It will look something like TPAB or TPBA followed by numbers. Write down the complete model and serial number, then enter both into the Repair Clinic model lookup tool. This ensures you get parts that fit your exact furnace configuration — igniter type, blower motor voltage, and control board all depend on the model.
Yes — Tappan, Intertherm, Miller, Gibson, and Frigidaire (HVAC) are all Nordyne brands and share many parts. However, some parts are model-specific, especially control boards and igniters. Always verify compatibility using your exact model number. The pressure switch, limit switch, inducer motor, and gas valve often cross-reference between Nordyne brands, but don't assume — confirm in the parts diagram for your model.
Not always. The pressure switch is a safety device that monitors airflow. Before replacing the switch, check for a blocked drain hose (condensation backup), a clogged inducer wheel (lint/dust buildup), or a cracked hose connection. Clean or clear these first. If the switch still trips after airflow is confirmed, the switch itself has failed and needs replacement. A new pressure switch is $20 to $40 and takes 10 minutes to swap.

On Tappan furnaces, look for the model number on the rating nameplate mounted on the side or front of the cabinet, often near the access panels. The label may also list the serial number, so copy the complete model number exactly, including letters, numbers, and hyphens. Use it in the model number search to pull up the parts matched to your unit. This filters Repair Clinic's full Tappan furnace parts catalog, not just one category, so igniters, sensors, motors, controls, and other parts shown apply to your specific furnace model. That means fewer wrong orders and a faster repair.
