Mini split problems

Hi, I'm having problems with my Coaire mini split system. It's been freezing up and spraying water, and at times ice cubes, from the indoor unit. This' often accompanied by a loud grinding noise. Also, the line-set, where it connects to the compressor, will freeze, and there's often a small pool of water underneath. Was hoping someone might be able to tell me what's going on with this thing. Just had it installed recently, and it's been doing this ever since. Thanks for your time.

One check your indoor fan is correctly running ( blowing a good quantity of air. Two look for oily residue around flare connectors indoor and outdoor usually indoor first. This indicates a leak. Thus why the ice . Good luck

    I'll check the line ends for leakage as soon as I get home. These are the do-it-yourself threaded ends which FWIU have a tendency to leak..

    Is it normal for my line-set to collect condensation? The guy that installed it made a mess out of the insulation around the line-set, lots of tears and whatnot.

    Haven't noticed any issues with the fan, but I'll check that as well.

    As far as I can tell the fan's working fine. I can't really access the back of the wall unit to check the connection. The whole thing's wrapped up with tape, oily and dripping wet. I can't feel anything oily on the other end of the line where it connects to the compressor, but all the exposed copper line at that end has been completely covered in ice.

  • Dane-1 Nov 30, 2013

    Just cut a slit in the tape , where it meets the insulation the two flare nuts will be underneath , normally the larger of two pipes will be loose or poorly flared. If it\'s oily you will need to repair leak and recharge with refrigerant. Cheers Dane

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.

Hi, warning light on the central display of the indoor unit Coair A/c mini split blinks continuously, and unit does not respond to on/off. What is the reason and how to solve this problem


Try unplugging for 30 minutes and plugging back in. Make sure remote has fresh batteries, make sure timer setting for proper time is accurate. A power source running nearby may cause this unit to malfunction. If you don't have auto start, all you should have to do is press the remote 'on' button once power is restored. Here is a link to your manual. http://media.hydroponics.net/item-documents/coaire/coaire_UserGuide-1.pdf

Ice hitting outside fan


It sounds like your system might be low on coolant. Check the pressure of the main line and check it against the specs. You may have a leak in the system.

Mini split drain trouble


There is a temp. probe on the inside unit.(evaporator). If you open the front panel you should see 2 white air filters. With the right side one removed you should see a black probe on the coil. Possibly that probe needs replacement. Very possible there is also a defrost sensor connected to the outside condensing unit. That sensor is connected via a white plug in connector.. Replace that one too if possible.

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

English instructions for saivod fhs186 ice maker


DO THE BASICS:
Change the water filter
Add ice machine cleaner and go by the directions.
What should be kept clean?
There are 5 things to keep clean:
1. The outside cabinet & door.
2. The ice storage bin.
3. The condenser.
4. The ice making system.
5. The ice scoop.
The ice storage bin should be sanitized
occasionally. It is usually convenient to sanitize the
bin after the ice making system has been cleaned,
and the storage bin is empty.
A sanitizing solution can be made of 1 ounce of
household bleach and two gallons of hot (950F. -
1150F.) water. Use a clean cloth and wipe the
interior of the ice storage bin with the sanitizing
solution, pour some of the solution down the drain.
Allow to air dry.

How to clean the condenser.
The condenser is like the radiator on a car, it has
fins and tubes that can become clogged. To clean:
1. Remove the kickplate.
2. Locate the condenser surface.
3. Vacuum the surface, removing all dust and lint.
Caution: Do not dent the fins.
4. Replace the kickplate.
Winterizing
1. Clean the machine as explained on the next
page.
2. Turn off the water supply.
3. Drain the water reservoir. See page 24, Spray
Pump Repair and follow the instructions to remove
the pump hose (step 2, bottom hose only).
4. Disconnect the incoming water line at the inlet
water valve.
5Remove control box cover and turn the timer
into the harvest cycle.
6. With the machine operating, blow air through
the inlet water valve; a tire pump could do the job.
7. Drain pump models should have about 1¤2 gallon
of RV antifreeze (propylene glycol) poured into the
ice storage bin drain.
Note: Automotive antifreeze must NOT be used.
8. Replace control box cover. Switch off and
unplug the machine.

CUBE ADJUSTMENTS
There are three items that may be adjusted: Cube
Size, Harvest Time, and Bin Level. Note: Cube
Size and Harvest Time adjustments should only be
done by a qualified service person.
Cube size control.
The cube size control should only be adjusted to
bring the cubes to the correct shape, the overall
size cannot be adjusted. Try to adjust the cube
size control when the ice machine is in the harvest
cycle, or in the first 10 minutes of the freeze cycle.
1. Open the door and remove the control box
cover.
2. Locate the cube size adjustment screw, and to
make fuller cubes, turn the screw clockwise about
1/4 turn. This will make the freezing cycle longer.
3. To shorten the freezing cycle and make cubes
that are not as full, turn the adjustment screw 1/4
turn counterclockwise.
4. After the next freezing cycle, the cubes should
have responded to the adjustment, if another
adjustment is required, do it early in the freeze
cycle.

This is a drawback of most mini-fridges. Start by defrosting everything. Then fill ice cube trays with water and keep lowering the setting until the water freezes. Just go a little lower, no more. Fridge should not freeze food. If the fridge stays closed all the time food will freeze. Also if the freezer element gets ice buildup it must be defrosted. Not automatic like home fridge. Most kids today weren't born when the last fridges that had to be defrosted were in service.

Ice cube tray not releasing cubes


The ice maker system is pretty simple.. A motor rotates with a gear reduction system and as it rotates... a switch is tripped when the motor reaches a certain point on its rotation... that switch lets water in for a prescribed period of time ( normally that is adjustable) and then as the motor rotates some more.. the ice tray has had adequate time for that ice to freeze and is positioned for it to be released,..at that time.. a small heating element is energized to release those ice cubes and the cubes fall from the tray into the bucket.. Chances are your heater is not working, unplugged or defective.. I would start by thawing everything out and getting the system free of any and all ice.. If after you've cleaned it all up.. and it still fails to release ice..you could be over-filling your tray and that freezes .. which in turn causes the system to fail too..You may need to adjust the fill level by throttle back on the water or if your system has a fill level control.. adjust that.. but first things first.. get the system back to a known good state.. ( meaning free from all ice ) so that you can monitor its performance,. Hope that helps...

Water freezes before getting to ice tray


sounds as if your water inlet valve is not closing fast enough allowing a small amoutn of water to accummulate in fill tube freezing and eventually freezing solid, would try replacing water inlet valve, or even the water filter if this model is so equipped
