An overheating air conditioner is a tragic story. Your AC has only one goal: to make you feel cool and happy. Your AC will stop at nothing to achieve this, even if it means burning itself out in the process.
Overheating occurs when one or more of the AC’s components are not working the way they’re supposed to. The system will work extra to compensate for the damaged components, and that will lead to excess energy consumption followed by overheating. If you’re lucky, overheating will do no more than trip your circuit breaker. If you’re not so lucky, your AC will do its best before sadly breaking down.
