626547R Nordyne 320 degrees F, Manual Reset, SPST, Rollout Switch

OEM Safety Switch for Furnaces & Heating Systems

The 626547R is a genuine Nordyne OEM manual‑reset rollout switch rated at 320°F, designed to protect furnaces from unsafe burner or heat exchanger conditions. This safety device shuts down the system if excessive heat is detected around the burner compartment, preventing damage and ensuring safe operation.

⭐ Key Features

• OEM Nordyne part — not aftermarket

• Temperature rating: 320°F (manual reset)

• Switch type: SPST (Single‑Pole, Single‑Throw)

• Critical safety component for furnace protection

• Restores system operation once the underlying issue is corrected and the switch is manually reset

🔧 Function & Application

The rollout switch monitors temperatures around the burner area. If flames “roll out” or heat rises beyond safe limits, the switch opens the circuit to shut down the furnace. This protects:

• Heat exchangers

• Burners

• Wiring and controls

• The home from potential fire hazards

A tripped rollout switch often indicates an underlying issue such as:

• Blocked heat exchanger

• Restricted airflow

• Cracked heat exchanger

• Blocked flue or venting

• Improper combustion

🏷️ Compatibility

Used across many Nordyne, Intertherm, Miller, and Revolv furnace models. Always verify with model and serial number.

🛠️ Installation Notes

• Must be installed by a qualified HVAC technician

• Manual‑reset design requires physical reset after correcting the cause

• Never bypass or jumper a rollout switch — it is a critical safety device
