   Ultimately, the older a heater gets, the less efficient it will become, so if the heater is 15 to 25 years of age, it may be time to start saving for an upgrade. 5. Clogged Air Filter

3. Electrical fault - Wikipedia

   en.wikipedia.org/wiki/Electrical_fault

   A ground fault (earth fault) is any failure that allows unintended connection of power circuit conductors with the earth. [citation needed] Such faults can cause objectionable circulating currents, or may energize the housings of equipment at a dangerous voltage. Some special power distribution systems may be designed to tolerate a single ...

4. Failure of electronic components - Wikipedia

   en.wikipedia.org/wiki/Failure_of_electronic...

   In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the device, or open or short circuits. Failures most commonly occur near the beginning and near the ending of the lifetime of the parts, resulting in the bathtub curve graph of failure rates.

5. High resistance connection - Wikipedia

   en.wikipedia.org/wiki/High_resistance_connection

   A high-resistance connection (HRC) is a hazard that results from loose or poor connections in traditional electrical accessories and switchgear which can cause heat to develop, capable of starting a fire. [1] Glowing connections occur when relatively high current exists in a relatively large resistance object. Heat comes from power dissipation ...

6. Contact resistance - Wikipedia

   en.wikipedia.org/wiki/Contact_resistance

   Bad contacts are the cause of failure or poor performance in a wide variety of electrical devices. For example, corroded jumper cable clamps can frustrate attempts to start a vehicle that has a low battery. Dirty or corroded contacts on a fuse or its holder can give the false impression that the fuse is blown.

7. Troubleshooting - Wikipedia

   en.wikipedia.org/wiki/Troubleshooting

   Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
