Let’s Talk About Nordyne 626612R Limit Switch With Auto Reset 135 165 Degrees F
The Nordyne 626612R Limit Switch With Auto Reset 135 165 Degrees F is a seemingly small, but critically important component for many heating systems. Manufactured by Nordyne, this limit switch is designed to prevent overheating and ensure safe operation of your furnace or other heating appliances. Its auto-reset feature is what really caught my eye, as it promised to eliminate the need for manual intervention after a minor overheat event.
My old furnace was acting up, shutting down unexpectedly. The HVAC tech pointed to a faulty limit switch as a likely culprit, recommending I replace it preemptively. After researching various options, the Nordyne 626612R Limit Switch stood out due to its specified temperature range and auto-reset capability, saving me the headache of a manual reset every time the furnace hiccupped.
Upon receiving the switch, my first impression was positive, the materials felt robust and well-made. Although it’s a small part, the quality seemed immediately apparent. The compact design also assured me it would fit easily into the existing space in my furnace.
Compared to a generic limit switch I considered from a local hardware store and a slightly pricier, digitally controlled option, the Nordyne 626612R Limit Switch struck the perfect balance between reliability, ease of installation, and affordability. The digital option seemed overkill for my needs, and the generic switch lacked the auto-reset feature I was looking for. I was definitely excited to see if this simple component could solve my furnace issues.
Real-World Testing: Putting Nordyne 626612R Limit Switch With Auto Reset 135 165 Degrees F to the Test
First Use Experience
I installed the Nordyne 626612R Limit Switch in my home’s forced-air furnace during a particularly cold snap last winter. The installation process was straightforward; it was a simple disconnect and reconnect. The switch fit perfectly into the designated spot, and I was able to complete the replacement in under 15 minutes.
During the initial week of testing, the furnace operated flawlessly. The true test came when a temporary blockage in the ductwork caused the furnace temperature to spike. The furnace shut down as expected, but the auto-reset feature kicked in and brought the system back online after it cooled down, preventing a prolonged outage in freezing temperatures.
Extended Use & Reliability
After several months of continuous use, the Nordyne 626612R Limit Switch continues to perform reliably. I’ve noticed no degradation in performance. The furnace starts and stops as it should, and I haven’t experienced any unexpected shutdowns related to overheating.
The switch itself shows no signs of wear and tear. The bimetallic strip inside seems to be holding up well to repeated temperature cycles. Maintenance is non-existent; it’s a set-it-and-forget-it component. Compared to the old, unreliable limit switch, the Nordyne 626612R Limit Switch has been a major improvement, providing peace of mind during the winter months.
