Troubleshooting Common Fedders Air Conditioner Problems

If your Fedders air conditioner isn’t working properly, there are some troubleshooting steps you can take before calling a professional. As one of the most popular air conditioner brands, Fedders units have many useful features but can develop issues over time. This guide will walk you through solutions for the most widespread Fedders AC problems.

When technical problems arise, don’t panic. Oftentimes, minor troubleshooting and maintenance can get your Fedders air conditioner back to pumping out cool, comfortable air. We’ll cover common issues like AC not turning on, AC not cooling properly, strange smells, odd noises and more. We’ll also provide tips to maximize efficiency and lifespan. Let’s begin!

Air Conditioner Not Turning On

Having your air conditioner refuse to power on can be immensely frustrating on hot days. Here are the most common reasons a Fedders AC unit won’t turn on:

  • Power Issues – Check your home’s electrical panel for any tripped switches or blown fuses. Ensure the unit is plugged in securely. Try resetting the air conditioner by turning the power off via the breaker, then back on after a minute.
  • Power Button – Make sure the AC power button or switch is actually in the “On” position. This may seem obvious but is overlooked surprisingly often.
  • Capacitor Problems – Faulty or old capacitors prevent proper power flows. Capacitor issues can arise unexpectedly. Testing capacitors involves specialized tools, so this may require hiring an HVAC technician.
  • Control Board Failure – Like any electronic device, control boards can short circuit or stop functioning properly. Have an expert diagnose control board problems. As complicated components, repair costs can be high for control board replacement but this is sometimes necessary.

Air Conditioner Not Cooling Properly

What good is an air conditioner that can’t keep your home nice and chilled? Insufficient cooling is one of the most reported Fedders AC problems. Try these tips when your system underperforms:

  • Clean Filters – Dirty filters block airflow, reducing cooling capabilities. Clean or change filters every 1-3 months for optimal operations. Disposable filters should be replaced entirely.
  • Refrigerant Leaks – Low refrigerant levels make cooling impossible. Unfortunately, refrigerant leaks aren’t DIY fixes. Certified HVAC technicians have the tools and expertise to identify leaks and top off refrigerant levels safely.
  • Drainage Issues – Condensation drips from ACs during cooling cycles. Drain pipes sometimes get blocked, causing moisture buildup and reduced performance. Carefully pour drain cleaner products (like vinegar or bleach) into the condensate line to open clogs.
  • Fan Problems – Faulty blower fans prevent air circulation for heat transfer. Electrical issues or worn out bearings usually underlie blower fan failures. Time for a professional diagnosis!
  • Compressor Failure – The compressor is the heart of an AC unit. After a decade or more of use, compressors burn out. When replacing a compressor, the whole system should be checked over too.
  • Thermostat Adjustment – Make sure your thermostat is set lower than the indoor temperatures. Compatible smart thermostats allow for finer temperature control and scheduling.

Strange Smells from Air Conditioner

Odd or unpleasant odors emanating from your indoor air conditioner are possibilities for concern. Common causes of AC smells include:

  • Mold and Mildew – Dark, damp AC interiors encourage mold growths. Musty smells signal mold accumulation. Have HVAC technicians thoroughly clean the system’s ductwork. Proper airflow is crucial for preventing future mold issues.
  • Critters and Pests – Rodents or nesting birds sometimes get into AC components. Droppings and debris create foul smells. Pest removal services may be required prior to additional repairs.
  • Electrical and Burning Smells – Burning plastic odors typically stem from problematic wiring or overloaded systems. Ensure your AC unit’s electrical specifications sufficiently match your home’s circuits. Turn off the unit immediately if you detect burning.
  • Gas Leaks – Since some Fedders units contain gas for heating, leaks are hazardous. Gas smells like sulfur or rotten eggs. Avoid turning electrical switches on or off (which can spark fires) and evacuate the building if you suspect gas leaks. Call emergency HVAC technicians for assessment and repairs.

Noisy Air Conditioner Operation

Hearing odd sounds like banging, squealing or grinding from your operating air conditioner is worrying but usually manageable through troubleshooting. Potential sources of noisy Fedders ACs:

  • Imbalanced Fans – Air circulation depends on fans rotating smoothly. Imbalanced fan blades or worn out bearings create excessive vibration and noise during fan operation. Fan repairs or replacements may be worthwhile.
  • Compressor Issues – Faulty pistons or bearings inside damaged compressors can generate knocking, squeaking or rattling noises. Diagnose compressor problems promptly since they can lead to full breakdowns.
  • Loose Parts – Various loosened internal components like fittings, screws or sheet metal can cause clattering commotion. Track down and carefully resecure any detached hardware or brackets bouncing around inside the AC.
  • Electrical Problems – Electrical shorts and arching issues often produce a buzzing racket. Possessing adequate circuit capacity is key for preventing such defects. Professional investigations are crucial for recognizing electrical faults.
  • Blocked Lines – Refrigerant flow disruptions make components loudly cycle on and off. Blocked piping and clogged condenser coils should be cleaned properly to silence this noisy cycling.
  • Icing Up Issues – Some air conditioners accumulate frost or ice, indicating low refrigerant or airflow problems. Check that cooling fins and filters aren’t excessively blocked if you hear unusual sounds only when ACs ice up.

When to Call HVAC Professionals

While following troubleshooting guidance can resolve temporary hiccups, major AC repairs eventually require contacting qualified HVAC (heating, ventilation and air conditioning) technicians for service calls. Beyond technical expertise, specialized tools and testing capabilities, seasoned professionals know Fedders products inside and out.

Seeking professional assistance is recommended when:

  • Safety is a concern – gas leaks, electrical issues, carbon monoxide releases
  • AC problems reoccur regularly
  • Performance declines over time instead of resolving
  • Strange noises or smells persist
  • You lack the time, skill or physical capability to self-troubleshoot
  • Problems worsen noticeably

additionally, long-term preventative maintenance from HVAC pros promotes air conditioner health and longevity. Sticking to yearly maintenance schedules minimizes regrets down the road.

Following best practices allows Fedders ACs to remain operational for over a decade, depending on model. Here are pro tips for extending your system’s lifespan:

  • Strategically replace filters as needed to enable adequate airflow and prevent strain on internal components.
  • Clear debris and overgrowth away from condenser units outside which could obstruct airflow.
  • Shut down ACs before the coldest winter weather arrives to avoid weather-related damage.
  • Consider installing protective weather shelters over exterior condenser units.
  • Address leaks, drips or moisture accumulations promptly to inhibit corrosion, mold and pests.
  • Verify your home’s electrical system has sufficient amps for powering AC capacity to avoid overstraining circuits.
  • Level out any soil, grass or concrete underneath condenser units every couple years to maintain proper positioning.
  • Take quick action whenever operational changes arise like unusual smells or sounds. Early intervention prevents cascading failures.
