Amana, At a Glance
Born in 1934, Amana has been designing and manufacturing reliable heating and cooling products for almost 100 years. The brand has been repeatedly recognized as the producer of some of the most energy-efficient systems on the market, thanks to their exceedingly impressive ratings and ENERGY STAR® certifications.
Additionally, Amana air conditioning products are backed by the brand’s extensive warranty coverage to ensure that Canadian homeowners can rest easy should any issues arise.
Remembering to replace your Amana unit’s air filter regularly will significantly lengthen the air conditioner’s life. Additionally, frequently vacuuming the registers and keeping the area surrounding your air conditioner free of debris will contribute positively to your system’s performance. These simple practices will guarantee efficient and long-lasting cooling comfort.
How to Replace Your Amana Air Filter
Follow these simple steps to replace your Amana air filter:
- Turn off the system’s power
- Open the panel to gain access
- Find your air conditioner’s filter. Usually, these are located near the return air duct
- Remove the dirty air filter
- If it’s reusable, clean the filter, or grab a new one if you’re using disposable filters
- Reinsert the cleaned or new air filter
- Replace the access panel and turn the power back on
What’s Wrong With Your Amana Air Conditioner?
Remember to turn your a/c completely off before opening it up to look around or attempt any fix.
Is air not coming out of the floor and ceiling registers?
If there isn’t any air movement, check to see if the outside unit fan is operating. If it isn’t, you’ll have to see if the air conditioner’s breaker is defective.
Is the outside unit only blowing hot air?
If you notice that the compressor starts operating, but the fan doesn’t, the condenser fan might be defective. However, if the condenser fan works but the compressor doesn’t, the unit could either be low on refrigerant or have a defective compressor.
If the blower motor isn’t running, but the fan outside operates properly, then you should check to see if the blower motor is defective. Alternatively, there could be an issue with the control board or run capacitor.
Is your air conditioner providing insufficient cooling comfort?
If the compressor and condenser fan both seem functional, but your home doesn’t feel as comfortable as it should, then your system might require some maintenance. Measure your system’s temperature drop; if it reads significantly lower than it should, your air conditioner refrigerant charge may be defective.
On the other hand, if the reading is too high, then you should examine the blower motor, air filter, or evaporator coil – any of these components might be dirty or faulty.
