Troubleshooting Guide When it comes to figuring out what is wrong with an air conditioning unit, most people would prefer to leave it to a licensed professional. However, it is quite possible to repair simple problems by yourself. 1. The main problem usually occurs with the filter just inside the air conditioning unit panel. Most people can change the filter themselves, but they neglect changing their air conditioning filter once a month and it ends up clogging. Be sure to change your filter and try turning the unit off for a few hours to allow any ice to thaw. 2. In addition, a low freon pressure could also be the culprit. The ideal pressure reading should be around 65-70 psi, so you will need freon gauges to get a reading from the high side(the larger of the two freon lines). Freon can slowly escape from the outside unit over time. That is why the unit must be serviced occasionally. 3. When the thermostat is turned down low and the unit inside is not coming on at all, it could be caused by the condenser fan motor. Wire connections could be burning up or may have been loosened by vibration. When this happens, it needs to be replaced. From: Mark Henry<mhenry@hmail.com> To: Customer Service Department<customerservie@tgelectronics.com> Re: Air Conditioning Date: August 25 To whom it may concern, On July 2, I purchased an air conditioning system(model number 369). Although the product came with a one-year limited warranty, I spent an additional $130 and purchased a five-year extended warranty that covers all parts and labor. Two weeks ago I noticed that the air conditioning system was making a strange noise. A visit by the technician on August 10(invoice TB 5789)revealed that the air conditioning systems freon pressure was 50 psi. I was promised that freon gas would be refueled in under a week, but it ended up taking nine days for that to happen. I received a bill today for the cost of the freon gas and repairs. It is my understanding that parts and labor are covered under the warranty, so I should not have received a bill. I appreciate your attention to this matter. Mark Henry

What is the purpose of the document?

A．To explain how to install an air conditioning

B．To inform. users how to deal with mechanical problems

C．To advertise a new air conditioning system

D．To report a damaged air conditioning to a repair center
