This can only be a gas problem.
the split units goes on on and off if a shortage of gas is involved, the chances that you would here it wont be that big for the fans would make too much noise.
get a repair man for a re gas and all is well.

Good luck.

Wouter.

On a heat pump the difference from heat to cool is the reversing valve.
In cooling or heating the Y1 terminal will always be energized, this is the contactor.
Depending on brand the reversing valve will either be energized in Heat or Cool. At the outdoor unit check to see if the reversing valve is getting 24 volts in cool, if not check to see if it is getting 24 volts in heating. The easiest way to check if the reversing valve is shifting, is to feel the big copper tube, (it is not the suction line on a heat pump) this is a refrigerant vapor line. It will be cold in cooling and hot in heating.
Check your thermostat installation instructions and heat pump installation instructions to determine the proper terminal designations for your heat pump and thermostat. There are some brands out there that use the B terminal as common to the 24 volt circuit, so you have to check the wiring and make sure this is not common.
If it is energized in Cool then the Y1 and O terminal will be energized. You will have 24 volts from common usually the C terminal to Y1 and O.
If it’s energized in Heat then the Y1 and B terminal should be energized. You will have 24 volts from common usually the C terminal to Y1 and B.
If you get heat when you’re calling for cooling or vice versa then switch the wire between the B and O terminals.

What does H1 code indicate?


Hello E, I appreciate your post!
I see that your Frigidaire air conditioner is displaying an error code of "H1". I have reviewed the air conditioner and the "H1" error code could be an "HI". The "HI" error code means that the room temperature is above the display range. I would recommend performing a reset on your air conditioner. In order to reset the air conditioner you need to unplug the power cord you can press the reset button and then the test button that should restart your air conditioner. If that does correct your issue I would recommend seeking assistance from a professional technician for proper diagnosis and repair. I hope this information is helpful for you. -Matt

No power at interior unit. power everywhere else


If this is a mini split ductless there is a control wire with 3-4 wires inside (normally red, white, blue and green) that is connected from the outdoor unit to the indoor unit. This wire feeds voltage from the o.d. unit to the I.d. unit. If all connections at the o.d. unit are good, then check for voltage at these connections at the o.d. unit. If no power at these connections then a circuit board has faulted. Call a tech. and have a tech support number ready (1-800#) in case your service tech don't have it.

Not cooling good and has an odd smell.... We've repaired a leak in freon in 2 places in the last 2 months!! ugh!!! I'm so frustrated with this thing.... it was cooling like a dream when we first installed...


Where were the leaks in the system. If they were in either the indoor or outdoor coils, I would replace the entire system. If they were in the refrigerant lines that connect the indoor and outdoor units, I would replace the line set only.

I have a Mitsubishi heat pump that runs well but the outdoor unit does not defrost what could be the problem.


Why does my heat pump ice up in Winter?
Heat pumps naturally ice-up in the winter. It is normal for the entire coil to be covered in a white frost and even light ice, during cold weather conditions. However, it is bad for the entire unit to be encased in ice. This indicates ductless heat pump problems which should be addressed quickly to save energy and avoid serious damage to your ductless unit. These systems should periodically go into a defrost cycle. This keeps the unit running efficiently. If the coils are blocked by ice, proper heat transfer between the coil and the outside air will not occur.
How does the defrost mode work?
When the mini split heat pump goes into defrost, the reversing valve inside of the outdoor unit is energized, switching the system from heat to the air conditioning mode. The outdoor coil becomes the hot, the indoor coil becomes cold, and both - the outdoor and indoor fans shut off. This allows the outdoor coil to melt accumulated ice. When the built-in micro-computer analyzes that all ice have been melted, the heat pump heating system goes back to heating mode.
sanyo-mini-split-defrost.pngA cloud of water vapor may be seen rising over the outdoor unit and a "whoosh" sound can be heard as the refrigerant reverses direction. The entire process usually takes up to 10 minutes (depending on conditions).
How often does the system goes into defrost mode?
Ductless mini-split heat pumps have different ways of determining when to go into defrost. The built-in microcomputer determines outdoor temperature, refrigerant pressures, and several other factors. In colder temperatures the system will go into defrost more often than in warmer.
If a ductless mini split heat pump is severely iced-up in the winter it is possible that it isn't defrosting (though there could be many other causes). Let the manufacturer certified technician check your system
