Real-World Testing: Putting Nordyne 626598 Main Limit Switch M7Rl 072 to the Test
First Use Experience
My first experience with the Nordyne 626598 Main Limit Switch M7Rl 072 was during a routine furnace inspection in a small cabin nestled in the Poconos.

There were no visible signs of wear and tear on the switch, despite the cabin experiencing fluctuating temperatures and humidity levels throughout the seasons. The switch appeared to be well-protected from the elements within the furnace housing. The part looks as good as new months later.
Maintenance is virtually non-existent for a limit switch. A quick visual inspection during routine furnace maintenance is all that’s required. Keeping the surrounding area clean of debris is essential for proper airflow and preventing overheating in the first place.
Compared to some cheaper aftermarket limit switches I’ve used, the Nordyne 626598 Main Limit Switch M7Rl 072 significantly outperforms them in terms of reliability and accuracy.
