Question about Sanyo 12KS51 11800 BTU Cooling Only Mini Split Air Conditioner with Clean-Air Filter

Open Question

I have a Sanyo Flexi-Multi Series CMH3172 that allows four evaporators but I only have two evaporators connected now one 9btu and a 12btu. It very new but one of the units 9 btu blows cold air for a while and than goes off blinking and the other unit just blows out un- cold air. My installer who came back once before to add Freon said I should reset the handheld remote controls. The remotes allow you to turn the system on and off and change things but it does not seem effect the tempture setting.

SOURCE: REMOTE CONTROL SYMBOLS?

Hi there,

To be honest.....I didn't think that I'd actually have to pay just to see a photo of the couple of buttons on a remote saying what their function is. A team of experts isn't needed for this. We purchased and moved into the house recently and the previous owners didn't leave us the manual so we don't know what button does what.......
If someone would be so kind as to tell us, that would be great. Otherwise....thanks anyway.

Sincerely,
R.L.B.

Wht is a TXV


Simply it's a valve in a refrigeration system that controls or meters how much coolant is allowed into the evaporator.
A thermal expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in refrigeration and air conditioning systems that controls the amount of refrigerant flow into the evaporator thereby controlling the superheating at the outlet of the evaporator. Thermal expansion valves are often referred to generically as "metering devices".
A thermal expansion valve is a key element to a heat pump; the cycle that makes air conditioning, or air cooling, possible. A basic refrigeration cycle consists of four major elements, a compressor, a condenser, a metering device and an evaporator. As a refrigerant passes through a circuit containing these four elements, air conditioning occurs. The cycle starts when refrigerant enters the compressor in a low pressure, low temperature, gaseous form. The refrigerant is compressed by the compressor to a high pressure-and-temperature gaseous state. The high pressure-and-temperature gas then enters the condenser. The condenser precipitates the high pressure-and-temperature gas to a high pressure liquid by transferring heat to a lower temperature medium, usually ambient air. The high pressure liquid then enters the expansion valve where the TX valve allows a portion of the refrigerant to enter the evaporator. In order for the higher temperature fluid to cool, the flow must be limited into the evaporator to keep the pressure low and allow expansion back into the gas phase. The TXV has sensing bulbs connected to the suction line of the refrigerant piping. The sensing bulbs give temperature readings to the TXV to adjust flow of refrigerant.[2]

IR Compressor sl.No N37 - 75KW NIRVANA -TEO179V05257 (oil free screw compressor). Machine trips with VSD 8 fault. Hall effect sensor is new one and is connected as per the correct sequence. Are there...


Yes, the control board may be bad . Ihave attached a procedure for checking the hall effect sensors, some of which you will not have the special tool needed to preform all the tests. However it will allow you to check the control board which may be bad causing your problem.

VSD FAULT DIAGNOSTIC GUIDE
10 Revision 001 - March, 2002
Appendix 4 - Hall Effect Sensor Checks (Four Part)
1. Isolate the compressor from the main incoming voltage supply. Lock and tag the
isolation switch in the open position.
2. Allow 15 minutes for the VSD to discharge capacitors.
3. Open enclosure doors to expose the VSD.
4. Check with a suitable meter that all voltages have dissipated before beginning work on
the VSD.
5. Remove rear cover of drive motor to permit rotating by hand.
TEST 1
6. Disconnect Hall Effect Cable from P4 on the Control Board, plug type is DB9 Type.
7. Inspect cable pins and matching receptacle connections for damage or bent pins.
Remove cover of plug and inspect solder connection of the wires for damage.
9. Inspect entire length of the cable for damage. If cable and connections are in good condition,
proceed to Test 2.
TEST 2
9. Confirm supply voltage to the Hall Effect Sensor is present using a digital multi-meter.
10. Disconnect terminal strips P1, P2 & P3 from the bottom of Control Board.
11. Trip and switch off MCB2 and MCB5 to prevent the SGN Intellisys from powering up.
12. Re-connect main incoming supply voltage to the unit. Isolation contactor KM1 should remain
de-energized and the VSD should only receive control power. Caution must be taken as the
panel has voltage present.
13. Set digital multi-meter to DC Volts.
14. Connect Black probe of multi-meter to either of the 2 pins of P16.
Note: P16 is located on the Control Board, slightly less than half way down and towards the left side.
P16 is marked and described as 2 small bare pins. P16 is the ground connection for the Control
Board.
15. Locate the small transistor just above Pin 3 on terminal strip P1. The transistor has 3 pins on
the left side. The pins are numbered 1 at the top, 2 in the middle and 3 at the bottom.
16. Connect Red probe of multi-meter to Pin 3. The voltage should be between +11 and +14 Volts
DC.
17. If voltage is not present, replace the Control Board.
VSD FAULT DIAGNOSTIC GUIDE
11 Revision 001 - March, 2002
TEST 3
17. Connect special adapter XXXXXXXX between P4 on the Control Board and the Hall
Effect Sensor Cable.
19. Set digital multi-meter to DC Volts.
20. Connect Black probe of multi-meter to either of the 2 pins on P16.
21. Connect Red probe of multi-meter to Red wire of the adapter. Rotate motor by hand and
observe measurement. The meter should read between +10 and +12 Volts DC.
22. Repeat the test with the Black wire of the adapter. The meter should read between +10 and +12
Volts DC.
23. Repeat the test with the Yellow wire of the adapter. The meter should read between +10 and +12
Volts DC.
24. If voltage does not rise to between +10 and +12 Volts DC for any of the 3 sensors, replace the
Hall Effect Sensor Assembly.
TEST 4
25. Set digital multi-meter to Ohms.
25. Connect multi-meter between Purple and Green wires of special adapter XXXXXXXX. The meter
should show a resistance value of approximately 150 Ohms ± 20% (New Hall Effect Sensors)* at
70° F (20° C) ambient temperature.
27. If correct value is not confirmed, replace the Hall Effect Sensor Assembly.
Note: Two temperature ranges (130° C and 150° C) of Hall Effect Sensor have been used. Typically,
the 50/60hp (37/45kW) units use a 130° C sensor and the 75/100hp (55/75kW) units use a 150°C
sensor. All sensors have a small band near the sensor end of the cable.
The 130° C sensor has four digits such as 6622 on the band. The 150° C sensor could have either a
four digit number with a star on each side (*6752*) or a four digit number followed by a star and the
letter E (6752*E) or a four digit number followed by an E (7652E).

Air conditioning unit just stopped working , operation light blinking code 1, on a cmh3172, the ac guy sai blown pcb board, are they repairable or actually have to be replaced, he said everything else...


It is a common problem, usually associated with moisture physically on the board or improperly installed communication cable (18-22 AWG shielded stranded Cu cable required). The PCBs are tightly packed and are frankly not worth the time it takes to diagnose and repair them. Replace the PCB and make certain that the original install was done correctly with the correct materials.

My motorola i465 has a white screen can it be fixed?


Hello,

The reason your phone is having a white screen is because because there is a problem with the flex of the phone.

The flex is the cable that connects the screen to the panel of the phone.

To fix this, you have to follow the process below;
  1. Get the appropriate screwdriver,
  2. First remove the battery cover and battery. Remove the four screws you see.
  3. Push the phone from the battery compartment to separate it into two parts.
  4. Now remove the four Phillips screws you can see.
  5. Carefully lift off the panel of the phone,
  6. Push up the screen to an angle, then you disconnect the flexi cable that links the screen to the panel,
  7. Carefully remove it and replace it with a new flexi cable,
  8. Reverse the process to reassemble the phone back together.
Take care

Hi, can not listen when somebody call me


Hello,

The reason you cannot hear the caller is because the speaker is faulty.

To fix it,
  1. Remove the four rubber stoppers surrounding the screen to reveal four screws. Remove these screws,
  2. You can now remove the front cover. To do this, use a credit card to lever the cover up. The cover clips on and the levering motion will unclip it. Start at the top, then unclip the cover at the bottom, then both sides.
  3. You should now have the front cover removed,
  4. Remove the rubber part which surrounds the camera. You should be able to lever it out with a fingernail or pen lid,
  5. Now detach the camera from the phone. Simply pull the ribbon away from the phone to release it,
  6. Now unplug the other ribbon, indicated wit a flat tip screwdriver, The ribbon attaches like a plug and socket. Simply lift it up to unplug it.
  7. The lens, is held to the phone with double sided tape. Pry it off. It will be stuck on well so some force is required.
  8. You now need to peel the brown flexi cable part away from the edges of the screen. Again, it is stuck on with double sided tape.
  9. The screen will now be free from the rest of the phone.
  10. Now remove the brown flexi cable entirely and you are left with just the LCD screen. it is on the brown flexi you have your speaker.
  11. so get a new flexi.You should now stick the flexi cable onto the screen.
  12. Reverse the whole procedure for reassembly.
You can as well use a ear piece for the time being before the repair of your phone

Take care.

Why must voltmeter be connected in parallel w/ circuit component


When connected in parallel it reads the voltage drop across said component.
When connected in series the current flows thru the meter allowing the measurement of the current flowing thru circuit.
Hope that helps.
