I have a fujitsu asta18lcc when you turn it on there is no operation. The louvers open and the timer and operation lights blink 5 times then there is a 6-7 second pause then the cycle repeats


Below is an extract straight from the fujitsu service manual:

Compressor location error
The compressor speed does not synchronze with the control signal. (Including start up failure of the compressor).
> permanent stop.
[Diagnosis Point]
Check if 2-way valve or 3-way valve is left open.
Check the compressor (Winding resistance value, loose lead wire).
Refrigeration cycle defective (Refer to after mentioned "refrigerant cycle diagnosis")

Where is the low pressure switch for my Honda Odyssey 2003 AC ?


The A/C pressure switch is located in the high pressure line (the skinny one) on the passenger side of the engine compartment just under the fuse/relay box. The switch has three functions: <28 psi, the switch opens to protect the compressor from lack of lubrication. >220 psi, the switch shifts the radiator and compressor fan to high speed. >455 psi, the switch opens to protect the compressor seals. Check to see if you have any powertrain DTC's first. A faulty engine coolant temp sensor can cause problems with the compressor clutch relay. If the radiator and compressor fan come on with the A/C on but the compressor clutch does not operate, check the compressor clutch relay. You can also obtain Heater control panel diagnostic trouble codes (DTC's) by turning the ignition switch on. Then turn fan switch off. Press recirc button to select recirc air. Press and hold recirc to turn off recirc air but this time continue to hold the button down until recirc light comes on for two seconds and then goes off. If there is any trouble, the recirc light will then blink a code (if no trouble, the light will remain off) 1 blink = problem in air mix control motor circuit. 2 blinks = a problem in mode control motor circuit. 3 blinks = a problem in evaporator temperature sensor circuit. (this one could be a factor in your case) Turn the ignition switch off to end the test.
