High Limit Thermostat - Limit 250-40

Hello Charles, thank you for your question. Set your multimeter to the R X 1 setting. Take each of your meter's probes and touch one to each terminal. You are testing for continuity, and you should receive a reading of either zero or infinity. At room temperature, testing the thermostat should produce a reading of zero. But if a thermostat is tested when it is heated to its limit, a reading of infinity should be produced. We strongly recommend that you test your thermostat at room temperature. If the test you conduct with your thermostat does not produce these results, then you should replace the component. I hope this helps!

Hi Mario, Thank you for your question. It very well could. I would suggest testing your thermostats to see if they are working correctly. You can do that using a multi meter. Good luck with your repair.
