Take a look at your electrical panel, and if a switch is out of line, flip it back. This might be all you need to do. But if the circuit breaker keeps tripping when the furnace runs, it\u2019s a sign of an electrical problem in your heating system, and you will need <a href=\"\/service-areas\/brentwood-tn\" target=\"_blank\" rel=\"noreferrer noopener\">heating repair in Brentwood, TN<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 2: Is the Thermostat Set Correctly?<\/h2>\n\n\n\n<p>It happens all too often: we get called to the home of someone whose heat isn\u2019t working, and we find that there\u2019s been a simple mishap with their thermostat. They could have adjusted it themselves and solved their problem in a matter of seconds if only they had checked their thermostat settings.<\/p>\n\n\n\n<p>On many thermostats, it\u2019s easy for a slight bump to jostle it from the heat position to the off or cool position. It\u2019s also possible that, either by total accident or through the meddling of a curious small child, a vacation setting has been activated. Your thermostat might be keeping the house cooler than usual in accordance with that setting. Or you might simply need to replace your thermostat\u2019s batteries.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 3: Is the Furnace Air Filter Clogged?<\/h2>\n\n\n\n<p>A clogged air filter prevents proper airflow through your furnace. This means that the heat your furnace creates gets trapped and builds up rather than being quickly distributed throughout the home. That excess heat can trigger the limit switch, which recognizes a safety risk and shuts the furnace down. Try cleaning your air filter\u2014which should be done monthly during the winter\u2014and see if your furnace works better now. This is one of the<a href=\"https:\/\/www.covenantheatingandcooling.com\/blog\/heating-service\/the-best-way-to-prevent-heating-repairs\/\"> best ways to prevent heating repairs<\/a> before they become costly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 4: When to Call a Furnace Repair Technician<\/h2>\n\n\n\n<p>You\u2019ve done what you could. Now it\u2019s time for a heating technician to come and investigate the issue. With their training and expertise, they\u2019ll be able to diagnose the cause of your heating failure and perform the necessary repairs. <a href=\"https:\/\/www.covenantheatingandcooling.com\/blog\/heating-service\/heed-end-of-season-heating-repair-needs\/\">End-of-season heating service<\/a> is especially important in spring to prevent lingering issues from affecting your comfort next winter.
