Question about Mitsubishi MS15TN Air Conditioner

Open Question

The indoor fan coil unit was on itself and blow the maxium wind. The remote cannot control it, need to off the main switch. What's wrong?

Very recently, the Mitsubishi Heavy ACM-SCM60ZG-S inverter system I purchased a few years ago gave a problem. One of the fan coil unit could be on itself and blows the maximum strength wind. It was unable to use remote to control it (remote works fine). I have to switch off the fan coil unit by off the main switch. Does this means the life span of the aircon? Need expert advice. Appriciate any input.

SOURCE: Error code E39 for Mitsubishi Heavy Industry Ceiling cassett type

E39 Fault is thermister, Mitsubishi way of saying im not going to start because there is something wrong. Generlly it is compressor fault or short of gas. Im guessing if you turned the power out. Waited twenty seconds, turn it back on. Now if you go to the outdoor part. Wait exactly 3 mins. If you hear the compressor try to start and fail then it would more then likely be your compressor if you dont hear anything and the unit faults out it will either be a board or short of gas.

Either way If the unit is under five years old get a warrenty agent out to look at it.

Sorry I couldnt tell you for sure but MHI are very vague when it comes to fault codes

SOURCE: outside unit fan not turning no cold air inside.

Ok here we go. It is possible that the capacitor for that fan unit is out or the motor for that unit is out. Without the proper tools i.e. an electrical meter, there isn't really a way to test the unit. The remote should not have anything to do with the unit activating if the is a manual thermostat. I suggest checking to see if either the motor has gone bad or the capacitor has bit the dust. If you have the motor changed make sure to replace the capacitor

Good Luck on your repairs hope I helped you some\

Tip

A/c shuts off within 5 seconds whenever operate by remote.


Service your unit periodically for reduced breakdown. Due to defective indoor room sensor and coil sensor, it shuts off within 5 seconds whenever you switch on. Replace it. If indoor fan motor mechanism locked also same problem araised. Rotate manually blower wheel. If hard, it needs bearing replacement or fan capacitor or motor itself.

I have a neo plasma lg 7kw will not heat LG Air conditioner


Make sure the setting on the remote is correct . Sun symbol for heating. Make sure the filters are clean. On heating, the indoor unit will 1/2 open the flap but the fan shouldn't start. The outdoor unit should start and if working properly, will be blowing cold air. The indoor unit will open the flap fully and the indoor fan will start once it gets hot then you should feel warm air. If the outdoor unit is blowing warmish air, I would say the reversing valve coil has failed or one of the indoor temp or pipe sensors are faulty. If a sensor fails, a "CH" error should appear on the display.

Air conditioner fan is blowing but not air coming


If you mean that your OUTDOOR AIR CONDITIONER FAN MOTOR is blowing AND no air is coming out of the vents within your house, it clearly indicates to me that 1 of 2 things are wrong.

Either (1) your INDOOR AIR HANDLER is NOT running or (2) the INDOOR AIR HANDLER is running but your PLENUM has come apart.

If your INDOOR AIR HANDLER UNIT is NOT running, it could simply be the circuit breaker is OFF/TRIPPED and simply needs to be turned OFF; then turned ON. If that does not FIX your problem, then it is most likely your 5 micro-farad run capacitor for your indoor fan motor needs to be replaced. It will prevent your indoor fan motor from energizing. Worst case scenario would be your INDOOR FAN MOTOR has windings burnt and needs to be replaced. If your indoor air handling unit is equipped with a CONDENSATE VALVE CUT-OFF SWITCH, check to see if your drain pan is filled, thus energizing the switch. If the CONDENSATE VALVE CUT-OFF SWITCH is ENERGIZED, it will prevent the AIR HANDLER FROM energizing. That is the design and the reason for this valve.

Good luck.

AC unit wont work, inside coils are hissing but outside unit not turning on.


If thisnis a central air conditioner and there is hissing at the indoor coil then the compressor is running, it is possible that both fans are not running. The indoor motor may not run if the control board is bad, capacitor is bad or the motor itself is bad. The outdoor fan may have a bad capacitor or the motor itself is bad

I have a 42" wind


the first thing to check is that the remote control is working and the control panel of the fan itself are working probably and i think they did but you have to check first
this fan oscillating control button is not a mechanical connection like the regular fan so if you are not using it wrong(and i think you don`t ) an if all the buttons are working -except the oscillating function - (and i think they are ) turn that thing back and test it at the shop

Goodman heat pump the fan runs but blows the 3amp fuse


The 3 amp fuse is for you're control voltage only, which is 24volts,ac. Something in the control side of your unit has a direct short in it. Since I am not on site to help you find out what part is at fault, I will give you some things to check out.You say you're indoor fan runs. I can only assume when you put the thermostat fan to on and not auto. Since this is a heat-pump, and not a gas fired unit, you will have a few less things that are 24volts.You say it blows the fuse on both heat and cool. You or someone that may give you a hand needs to do a process of elimination. What you will need to do, is to check all of the 24v. components to see which is at fault. The 24volts via relays and coils are what controls the motors, compressor, ect. We know that the indoor fan is good. I would be looking at the contacter coil first, even though the thermostat is 24volts. Since the contacter controls the condenser fan motor and compressor, my guess would be the coil on your contactor is shorted. I am not sure if you're heat-pump is a package unit or a split? Either way, you need to open up the control section of the compressor section which on a split its the outdoor unit. On a package unit, its where the main power enters. That would be on what ever kind of Goodman you may have, the 220volts come in and each of the 2 hot wires connect to the bottom of the contactor.What to do 1st.What ever it is, a split or a pack unit, turn off the main power to unit, split, outdoor unit, pack, whole unit.Even if this is a split system, when you turn the power off to the outdoor unit, you will still have 24volts to it when you turn the stat on.The 24 volts comes from the fan center on the indoor unit. With all of the power off, look at the contactor. On each side you will see 2 wires to a copper coil. Pull off these 2 wires, and dont let them touch anything even though they are dead.Turn power back on and check the 3 amp fuse. It should be fine. Now, with the power turned back on, touch these 2 wires back to the coil.This should blow the fuse. If it does, that contactor needs to be replaced.I know this is a lot to check, but I am sure the contactor coil is shorted. You will have to buy one from a retail appliance store. Every wire must be put back in its original place. If you don't think you can test this, I would advise calling someone out. I know this is a long solution, but i am sure that is the problem. Let me know please. Good Luck,
Shastalaker7
Ps an electrical meter would be of a lot of use to you. One more thing, if the copper coil on the contacter is burned and black, just turn off all power and replace it. I am certain this is your fault.
