How To Solve Common Panasonic Aircon Codes?

The Panasonic aircon enjoys remarkable reception and positive reviews mainly for its efficiency in promoting indoor comfort. However, the aircon codes may fail to function from time to time and this can be quite distressing. Fortunately, most of these faults are very easy to troubleshoot since they result from common mistakes and conditions that are reversible. If your remote functions fail to induce the expected effect, you may need to troubleshoot a number of issues to return the syncing correspondence. Here are solutions to some of the common Panasonic aircon codes faults. If the solution does not work, it can imply serious problems that will demand professional repair and troubleshooting.

How To Solve Common Panasonic Aircon Codes?

F11 (reversing valve failure) –

caused by faults with outdoor PCB, reversing valve or Coll. Correcting all these causes can resolve F11 problems.

F17 (freezing standby units) –

can be due to expansion valve leakages or multi mode only. Check the valve to ensure it functions correctly and replace faulty or old ones with new products.

F90 (PPC failure) –

these are caused by faulty inverters or compressors. Check for proper functionality for both components.

F91 (refrigerator cycling issues) –

can be a result of blockages or low gas. Check to ensure there is fluid air flow. Regular cleaning and maintenance will resolve the problem unless it is complex which may require comprehensive troubleshooting.

F93 (abnormal compressor revolution) –

this mainly occurs when the compressor is running incorrectly and restoring the correct revolution will resolve the problem.

F95 (overheating outdoor coil) –

such issues are a result of blockages, cool mode, dirty condenser coil or low gas. Resolving the problem requires general cleaning maintenance and increasing gas levels.

F96 (overheating IPM or compressor) –

can be caused by dirty heat exchangers as well as excess or low gas charge. Dust off the exchanger and re-establish the ideal gas charge.

F97 (high compressor temperature and discharge) –

this issue occurs due to faulty compressors or low gas charge. Repair or replace the compressor and restore ideal gas charge to resolve the problem.

F98 (over current protection) –

can be caused by excess charge or problems with outdoor heat exchanger. Replace the exchanger and restore ideal gas levels as a resolution.

F99 (DC over current protection) –

such problems are caused by compressor failure, outdoor PC or power transistors. Diagnose problems with these three components to find reliable solution.

H11 (communication failure with) –

this is mostly a result of faulty wiring or other issues with OD or ID communications. Check for the wiring and ensure it has no defects. ID/OD communication failures may require technical troubleshooting from experts.

H12 (ID/OD compatibility problem) –

this is usually caused by over-indexed or under-indexed multi system. Correct the fault by establishing the correct index.

H14 (faulty indoor air sensor) –

can be a result of dirty contact surfaces, disconnected or faulty sensors. Remove and connect back the sensor and clean contacts. If the issue is not solved, seek professional troubleshooting or buy a new sensor.

H15 (faulty compressor sensor) –

this is caused by dirty contact surfaces, disconnected or faulty sensors. Remove dirt from the contact and reconnect the sensors to correct the code fault.

H16 (transformer faults) –

this can be caused by very low gas, faulty PCB or failing Power Transistor Module. Raise the gas level to correct and try to change the transistor module.

H19 (locked fan motor) –

this is usually a problem caused by faulty indoor PCB. Replace the PCB to correct or seek professional troubleshooting to determine why the motor is locked.

H21 (operated float switch) –

check for issues with the drainage and correct appropriately. Routine maintenance can resolve issues of operated float switches and H21 functions.

H23 (faulty indoor pipe sensor) –

the issue can be a result of disconnected sensors and/or faulty or dirty contacts. Remove dirt from the contact and reconnect the sensors to correct.

H27 (faulty outdoor air sensor) –

this is another common problem caused by faulty or dirty contact surfaces as well as disconnected sensors. Wipe of any dirt from the contact surface and reconnect the sensor to restore functionality.

H28 (faulty outdoor pipe sensor) –

this is yet another problem caused by disconnections or dirty and faulty contact surfaces. Resolving such issues involve removing dirt from the contacts and reconnecting the sensor.

H30/31 (faulty outdoor discharge sensors) –

wipe off any dirt from the contact surface and reconnect the sensor. If the issue is not resolved, it may be due to a faulty contact surface which can demand replacement.

H33 (incorrect connecting voltage) –

this problem can be caused by faulty wiring or incorrect connection voltages. Check for correct wiring and adjust the voltage to the recommended value.

H36 (faulty outdoor gas sensor) –

check for dirty contact surface, disconnected sensors and faults on the contacts. Remove dirt and reconnect sensors to solve the issue.

H37 (faulty outdoor liquid sensor) –

like most sensor issues, this is often a result of faulty or dirty contact surfaces and disconnections. Wipe off any dirt from the contacts and reconnect sensor to solve the issue.

H39 (abnormal indoor operation) –

this can be due to problems with the expansion valve or incorrect piping. Ensure the valve is functional and correct any piping mistakes to resolve the problem.

H41 (abnormal wiring and piping) –

this is caused when piping or wiring cross each other on a twin system. Ensure the wires and pipes are not crossed to enable seamless flow of electricity and air.

H92 (outdoor fan failure) -

fan failures are usually a result of faulty motors and PCB failure. You may need to replace both components to resolve the issue or seek professional troubleshooting to determine any other underlying problem.

H98 (indoor coil overheating) –

overheating problems can be caused by high indoor temperature, faulty filters and indoor coils. Open ventilation spaces and replace faulty or dirty filters with clean functional ones.

H99 (faulty cool mode) –

problems with indoor Cool-Dell are caused by a number of issues that include dirty filters, low gas and charge, low ambient temperature or indoor Coll. Correcting all the causes will solve the issue.

Conclusion

There are various other Panasonic aircon codes problems that trouble most home owners. The above list presents majority of the common problems. If the solutions provided do not resolve the issues, it may imply complex damages and problems that require quality diagnosis and troubleshooting. Nonetheless most code issues will not require expert troubleshooting and the briefly described solutions will restore normal functionality.
