0 Some furnaces have more than one limit. First you need to find the one that is bad, or in a lot of cases weak or intermittent. You should replace the bad limit with an oem type if possible. limits are very important for the safety of your family. These limits are designed to shut off the gas supply when the furnace gets to hot. This can be from a clogged filter to a slow turning blower motor. Find the correct part. turn power off. And replace limit.
