Are you in the North East region of US? For the pass 6 days I saw a lot of postings for furnace and humidifier failures. Partly is because the weather but the root cause is lack of maintenance. ==== User think LIFETIME Electrostatic air filter is maintenance free. That is not true. It's wash-able and need to be handle with care. Inspect the air filter and replace it.. ==== Lack of air circulation cause the furnace frame from burning efficient (BLUE FRAME) to orange / red color. Over time,the temperature sensor will be coated with carbon deposit and record a higher temp reading. They circuit will activate the fail safe and not allow the igniter to start on. In your case,limit switch shut itself off. Here is a LINK to pictures of Weather King temp probes and sensors. A clean filter and temp sensor will save you money. Dial back the furnace to 65F until you can get hold of the filter and clean the sensor. ==== If the MODEL TAG is still in plain view then please post it on reply. Please keep me posted on the fix via email.
