Common Questions and Answers

How does the Lennox 13W23 Limit Switch/Thermostat help ensure proper operation of the machine?

The limit switch/thermostat senses operating temperature and opens the circuit when heat rises beyond its rated threshold, protecting the HVAC system from overheating and unsafe operation. Its auto-reset switch action allows it to restore normal function once temperatures return to an acceptable range, which supports reliable performance and reduces unnecessary downtime in the HVAC system.

How can I determine if the Lennox 13W23 Limit Switch/Thermostat might require replacement?

The limit switch/thermostat may need to be replaced if the heating and cooling equipment frequently shuts down, overheats or cycles irregularly, which can indicate that it is no longer responding accurately to temperature changes. Physical signs can include visible wear, heat damage or corroded terminals and environmental signs may include long exposure to excessive heat, dust or moisture that could affect its operation.
