HI, I have three 12000BTU C&H aircons installed in my home. One of these is exhibiting the following condition in heating mode. 1. unit turns on and starts heating after about 2 minutes as per normal. 2. then fan stops or slows down and heating stops. The top light on the indoor unit starts blinking every 8 to 9 secs. This continues for a period of sometimes 3mins, sometimes up to 15 mins. 3. After this the light stops blinking and the aircon starts working normally. No error code is displayed and the the gas pressure was checked by the C&H local techs and found to be ok. This issue happens either early in the morning or late in the evening only. Operation during the middle of the day is normal. Any advice please?
Hello, my name is Tim Murphy I work with the local distributor as a technical support specialist. I read you had the refrigerant level checked. Unfortunately checking pressure levels is not an accurate way to verify proper refrigerant levels on mini split systems. The correct method for verifying a proper charge is to remove all the refrigerant, vacuum the system down to 500 microns then use a scale and weigh in the factory charge. From what I read it does seem like it might be low on charge. In heating the coil must maintain temp for the fan to run. What are the model numbers?
@@0komanji0 Hi Tim. thank you for your reply. the model number CH-S12FTXQ. According to the C&H local technician the pressure whilst running was 35Bar which he deemed OK. I will relay your suggestion next time he visits. I stress again that after this strange behavior period the aircon heats up properly so this maybe indicates that the gas is ok. What I find strange is the 9 sec blinking. Surely this must mean something? When the tech opened the external unit there was a label on the underside of the top cover indicating the faults possible for the errors displayed. Unfortunately this 9 sec blinking rate is not listed. When you refer to the coil can you amplify what system part this is? Would I be able to blow hot air over it to see if this speeds up the error clearance? thanks.
Flashing 88 can also mean the wiring between the air handler and compressor is wrong. Check to make sure that the wires on the indoor and outdoor units are in the same order. CH choice in wire colors can make that part a bit confusing.
I have P6 code on all 2 hunter and cooper mini split. Worked great first time last year winter. This year winter has come again and tried turn the heat on, it didn't do a thing. P6 code pops up. I checked the freon pressure and it's normal. AC still works. Now, how do you test the high pressure switch and low pressure switch?? What voltage is it supposed to have?
The proper way to check refrigerant levels would be to evacuate the system and ad a new charge by weight. Mini spit systems can range anywhere from 80psi to 160psi when running. So checking the pressures is not an accurate way to verify proper charge. For troubleshooting the pressure switches you will need to call Cooper and Hunter Tech support so they can guide you through the step by step process. Please note: When a mini split cools but does not heat or vice versa, that is a sign of improper charge. I would remove the freon and pressure test @ 500psi of nitro and find the leak. Again please call Cooper and Hunter tech support on their site. Cooperandhunter.us
I had heat guys came down to refill the freon but it wasn't low. But it still doesn't wanna heat up the room, I keep hearing the heat pump kicked off and on like every 5-10mins. And on mini split keeps popping DF every 5-10mins then when DF goes off and it ran another 5mins then P6 pops up. It was constantly doing that for hours. Then i turned it off, giving it up. Its brand new, only used for about a year. Then I noticed other side of heat pumped, it was iced over, what's causing that.
My first question is, how did the technicians check the refrigerant levels? Mini split systems fluctuate pressures anywhere from 70-160psi. The only approved method of verifying the refrigerant charge is to remove all the Freon and weigh in a new charge. The manufacture will have the factory charge in oz. written on the model number data tag. I have a feeling the charge is low. DF means defrost mode. And P6 is usually in reference to improper charge.@@kevinharrison7677

Skip to the .50 sec mark on the video. The problem is either main control board or fan motor. I would advise you have a certified HVAC tech call tech support for Cooper and Hunter so they can walk them through the troubleshooting.
The brand name is DELLA. It is a 12000BTU 25 SEER 230V the only numbers I can see are on the inside unit; I don't see serial numbers only (048-MS-T2312K-IN) and Intertek 3119233. I have a total of 5 mini split units. Two are the ones giving me problems temperature is in the 0, and with the wind factor, it feels like -12. I have had these units for 5 years. Thank you in advance for any information that can help me fix this issue
Unfortunately we do not offer that brand at Tropic Supply so I do not have any error codes or information for DELLA. Try a goggle search for "DELLA mini split error code EF" I found something that points towards the outdoor fan, but again I don't have any information on that system, but we have new Cooper and Hunter systems in stock ready to sell..... LOL ; )
I'd suggest cleaning the display and turning the display off then back on again by using the wireless remote. If that doesn't work you may need a new display board.
My Mia NG shows “df” randomly while I have it on heat. I didn’t have any problems when AC worked this summer,it’s a new unit and the heat cut outs randomly at times and sometimes displays “df”. Anybody can help?
Hello Larry thank you for your question. Your MIA is a heat pump system and when a heat pump is in the heating cycle, the transfer of thermal energy often involves significantly cooler outdoor air. Under some temperature and humidity levels, frost may form on the outdoor coil and can accumulate quickly. This puts strain on heat pump system and makes operation unnecessarily laborsome. In order to combat this, your heat pump has what is called a defrost cycle "DF" to eliminate the frost from the outdoor coil. When the heat pump goes into defrost mode, it momentarily reverses operation and goes through the “cooling cycle.” This forces warm air through the outdoor coil, warming it temporarily to remove the frost. This DF or defrost cycle will activate automatically as needed. Please note the system will not heat until the defrost cycle has completed. Hope this helps answer your question.
Possible causes. T2 Sensor failure / PCB failure / Low or Improper refrigerant charge. In most cases its cause by leaking flare joints. Leak check should be performed. Then the refrigerant most be weighed in for the charge to be correct. Charging by pressures in a mini split will most likely cause damage.
With out an error code it is hard to say. Can you answer a few questions? 1.) Is this a single or multi zone system? 2.) Brand make and model numbers? 3.) Does the condenser fan run. 4.) Are you sure you completely opened all services valves using a 4mmm Allen wrench? 5.) have you verified line voltage at indoor units and out door units? What is the voltage?
@@michaelkmiotek7909 swing mode is only motorized on the main louver that swings up and down. The left and right turning vanes are manually adjusted by hand. My next question to you is, does the main louver open and close when you power the system on and off? If the louver is not functioning at all then there may be a loose plug or a faulty motor that moves the louver. If the louver does in fact open and close then there may be an issue with the signal from the remote. I would suggest having a certified HVAC tech come out to diagnose the issue.
The freon pressure can not be properly checked unless the compressor is running. If the compressor is not running your gauges will display the standing pressure. This is not an indication of proper charge. If you are unsure whether or not your system has the correct amount of freon in the system. You must remove the existing freon, and then weigh in the proper freon charge by use of a charging scale. We highly suggest before recharging the system you perform and high pressure leak test and vacuum the system down to 500 microns. Please note the vast majority of freon leaks that form on mini split systems tend to be located at the flare joints. Hope this answered your question, and thank you for watching.
Cooper&Hunter has a 7 year warranty with an excellent tech support team ready to diagnose the system please have a technician contact Tech support at 786-953-6706 so they can determine what is wrong and get this resolved as soon as possible.
Have a EH 60 error code. This happened after I took apart unit. Before that unit was cycling on and off. No leaks. Found remote in follow me function and it was showing 32 degrees. I turned off but was still having same issue. Only thing I can think of was the temperature sensor being loose on indoor. It was late so I’m going at it again tomorrow.
@@All4ChristNone4me The sensors are based on resistance. If there was zero resistance due to the sensor being disconnected. The board will calculate the temp based off zero, which in this case seems to be 32 degrees or it may be the default temp with zero resistance.
@@MrPvPzmc Hello! That Error Code indicates a Mode Conflict. If you have a multi zone system, you need to make sure all of your indoor units are set to the same Mode (COOL, HEAT, or FAN).

For troubleshooting this error code please have a HVAC technician call Cooper and Hunter tech support to diagnose the system. Error Code P4 is defines as: An abnormal inverter compressor drive is detected by a special detection circuit, including communication signal detection, voltage detection, compressor rotation speed signal detection etc... Possible causes: wiring mistakes, IPM malfunction, Outdoor fan assembly faulty, Compressor malfunction, Outdoor PCB faulty.
High pressure protection or low pressure protection. Verify the condenser coil is clean and has adequate air flow. If that checks out then you may be low on refrigerant. You will need to call a certified HVAC technician to evacuate the system then recharge. The proper method to recharge the system is to remove the refrigerant and weigh in a factory charge. Adding refrigerant by adjusting pressures will result in damage due to over/under charge.
Depending on the unit model number P6 error code means low refrigerant level. Recommend having a licensed contractor perform a high pressure leak test.
That is either a bad thermistor, bad indoor board, or low on refrigerant. most likely you are low on refrigerant. It's recommended a HVAC technician verify proper charge by removing the refrigerant from the system. Then weigh in a new charge using the factory charge amount that will be displayed on the model data tag on the condenser. DO NOT JUST ADD FREON TO THE SYSTEM, THE REFRIGERANT MUST!!! BE REMOVED AND WEIGH IN A NEW CHARGE USING A SCALE.
@@michaelramirez4008 Depending on your model number that could be an overvoltage protection on either the line voltage or communicating voltage. Again a model number would be useful.
Low pressure protector switch off. System will return to normal when pressure is corrected and code will clear itself. Chances are you have a freon leak. System should be evacuated the pressure tested at 500psi. Then repair leak and weigh in new charge.
