1. Introduction
It’s so infuriating how the air conditioning might stop working in the middle of a heatwave, while the heating system works just fine. That’s a behavior that can really annoy owners of an EB17C HVAC unit. This blog will clarify why your EB17C’s A/C might stop functioning, guide you on what steps to take while troubleshooting, and when it’s time to call in the pros.
2. Most Common Reasons for Failure of Your AC But Heater Working Some times, the Heating system works fine while your A/C is not working. That got to do with the following causes:
Thermostat Setting: You may have made a minor wrong setting up or installed a faulty thermostat.
Refrigerant Low level or leakage: It means that there is low-level refrigerant in your system or refrigerant leaks, so A/C cannot blow cooled air.
Electrical Problems: The wiring, fuses, or circuit breakers can go bad and disable the A/C but enable the heater
Compressor Problem: Compressor failure is crucial in cooling and if the compressor isn’t working then the A/C isn’t. But the heater would be
Clogged or dirty air filters; constrained airflow can make the cooling diminished
3. What is an EB17C HVAC?
Now, to troubleshoot, let’s first understand what the EB17C system is. The EB17C is an HVAC unit widely used in mobile homes, manufactured homes, and some small homes. These systems are designed for providing both the functions of heating and cooling; indeed, they can be used all year round.
Like most HVAC units, EB17C systems have separate components for heating and cooling. In such a scenario, where the A/C does not work but the heat still functions, it more than likely means there is a problem in the cooling parts, which could even be faulty refrigerant or a malfunctioning compressor.
4. Troubleshooting Steps for EB17C A/C Problems
Step 1: Check the Thermostat
The most obvious thing would be to adjust your thermostat. Ensure the thermostat is set to “cool” mode and that the temperature is below the prevalent room temperature. Sometimes, switching the thermostat from “auto” mode to “on” mode can help you diagnose if the fan works. This may allow you to investigate airflow.
Step 2: Check Air Filters
A clogged or dirty air filter can impede airflow considerably, forcing the A/C to operate inefficiently, if at all. You should check your filter for dirt and replace it if dirty. Maintenance is an integral part of correct HVAC operation.
Step 3 Check Power Supply
Then you should check your circuit breaker or fuses to make sure that power is going out to your A/C unit. You might have systems for heating and cooling that are on separate circuits; so if a fuse has blown or a breaker has tripped, the A/C won’t work but the heat still will.
Step 4: Check Refrigerant Levels
It’s also possible that warm air is blowing if there exists a refrigerant leak. HVAC systems need an appropriate amount of refrigerant to work properly; in case the refrigerant level is low or leaking, your A/C will not cool it at the recommended rate.
Step 5: Check the Compressor
A compressor serves to move refrigerant about a system. If the compressor is not working, your air conditioning will not work, even if everything else is okay. Sometimes you may be able to listen for unusual noises or even a possible absence of sound from the outer unit, which could mean compressor failure.
5. How to Diagnose A/C Problems in the EB17C Unit
If the above doesn’t work, then diagnosing a problem in your EB17C system may require a bit more technical knowledge. Here are some things you would look for:
Check the Blower Fan: If the fan on the blower isn’t blowing well, it won’t be forcing air across the system. Check to see if the fan motor is running, and ensure that there’s no blockage.
Test Capacitors: The start capacitor assists in getting the A/C compressor to start operating. If this component is defective, the compressor won’t turn on and create cooling issues. A multimeter can decide whether the capacitor is working or not.
Test the Outside Unit: Condenser coils of the outside unit should be clean and free from debris or dirt buildup. When the condenser coils get dirty, it causes the A/C to overheat. This will shut down the A/C unit.
6. When to Call an Expert
If, after troubleshooting, your EB17C A/C isn’t still working, it may be high time to call in the professional HVAC technician. More complex issues could involve refrigerant leaks, faulty compressors, or electrical problems, which often require specialized tools and a higher degree of expertise.
A licensed HVAC expert will do the following things:
Examine your system thoroughly.
Replace or repair damaged parts, such as the compressor or fan motor.
Top off refrigerant and look for leaks.
Instruct how to maintain the equipment routinely so that it doesn’t fail again in the future.
Catch issues as early as you can before they become costly to repair, especially when your unit still has a warranty.
7. Conclusion
It is really frustrating to have an EB17C A/C unit breakdown where the heat is still working, but this is pretty common. The steps in this guide will allow you to diagnose the problem and, in most cases, solve it yourself. In case the problem persists, however, you should not hesitate to seek a professional HVAC technician who could diagnose and rectify the problem effectively.
With proper care, regular checkups, and replacement of filters, you can prevent many of the common problems that plague both heating and cooling systems and allow your EB17C HVAC unit to run efficiently all year round.
