A good Senville AC works optimally as expected. Unfortunately, this is not always the case as the AC may fail or one reason or another happens, users may end up incurring a lot of costs, especially on electric bills.<\/p>\n
The good news is that before it gets out of hand, the AC tends to warn you by registering specific errors. Here are some of the error codes to expect and what they mean.<\/p>\n
Senville AC records different types of errors. They are generally categorized into outdoor and indoor unit errors. Each of these errors requires a specific response. However, before finding a remedy for the problem, it is crucial first to understand and diagnose the issue.<\/p>\n
To better understand these errors, this article brings some of the most common ones. Here is a list of the most popular Senville AC errors that you need to know about.<\/p>\n
E0 – Senville Mini Split Error Code – <\/strong>EEPROM parameter error<\/p>\n Senville Error Code Definition: EEPROM parameter error. This indicates an electronic error. It can either be caused by a control board problem or by a problem with supply voltage to the heater.<\/p>\n E1 – Senville Mini Split Error Code – <\/strong>Indoor \/ outdoor communication protection error<\/p>\n The E1 error code indicates a communication error between the indoor and outdoor units. To determine its existence, check to see if the wires have been connected properly connected.<\/p>\n Ensure that these wires are not crossed from the indoor to the outdoor unit. Before finding a solution, you need to test the circuit board first. This will help you verify that your circuit boards function as expected.<\/p>\n Test the voltage frequency that exists between terminals S and L2 on the outdoor unit. Use a multimeter that is set in DC.<\/p>\n A good circuit board will show results fluctuating between – 50 v and + 50 v. In case the results show fluctuation on the positive side ex: (+10v +30v) or on the negative side ex: (-10v – 30v) only, then this is an indication that the outdoor board should be changed.<\/p>\n In case the voltage constantly fluctuates at ex: (-16v), consider replacing the indoor circuit board. You can also fix it by turning off the electric breaker for a few minutes, say 2 minutes. When you restore the power back, it will function properly if nothing needs to be replaced.<\/p>\n E2 – Senville Mini Split Error Code – <\/strong>Zero crossing signal error<\/p>\n This error code indicates that the AC has an abnormal voltage and frequency fluctuation. This could be triggered by an improper wire size or an inappropriate breaker size. In case the wire sizes re all correct, then the boards could be the problem. To know what the issue is, carry out several tests.<\/p>\n Test the outdoor and indoor boards using a digital multimeter.<\/p>\n Set the device on direct current and verify the voltage fluctuation between terminals L2-S or other models, between 2 and 3. The result should fluctuate between -50 and +50 VDC.<\/p>\n The outdoor motherboard will need to be replaced if the numbers on the result vary negatively or positively only. In case of constant fluctuation, then replace the indoor board.<\/p>\n E3 – Senville Mini Split Error Code – <\/strong>Indoor fan speed no control error<\/p>\n This E3<\/em> error<\/em> code<\/em> indicates that there is an indoor<\/em> fan speed malfunctioning. It can also be linked to a bad indoor<\/em> circuit board or a bad indoor fan motor.<\/p>\n Check that both the indoor and outdoor fans can spin freely and that they are not blocked. Once this is covered, test the circuit board, and the fan motor. For the indoor fan motor test, release the UVW connector.<\/p>\n Measure the resistance of the U-V, U-W, V-W. When the resistance is unequal to each other, there is an issue with the fan motor requiring replacement. If not, power the AC. When on standby mode, measure the voltage of pin4-5 in the feedback signal connector.<\/p>\n
