There is the possibility that the cycle load has become heavy and the
compressor has come loose. Check the compressor.
* In this case the LED may blink three times before stopping.
There is the chance that the cycle load has become heavy and the
compressor has come loose. Check the compressor.
* In this case the LED may blink twice before stopping.
Check to see that the control P.W.B. has 17V.
* The A cycle and the Bcycle are different brands. Be
sure to check the correct points for measuring.
The power source circuit is broken.
Replace the control P.W.B.
The power source or some other reason may have caused the microcomputer
to reset. Replace the control P.W.B. if the LED blinks once and then stops
frequently during operation.
* The LED blinks once after the power source has been inserted.
Check to see the approximate length of time it takes for the
compressor to stop after switching on and operating two or
three times.
* Wait for three minutes or more before operating.
Check to see the approximate length of time it takes for
the compressor to stop after switching on and operating
two or three times.
* Wait for three minutes or more before operating.
In the case that one of the compressor cables has become loose (or
broken), the compressor may work even if it is missing a phase. The
compressor occasionally operates in reverse if one of the compressor
cables has been connected improperly. Replace the cable or rewire as
appropriate.
The compressor switch fails if two or more compressor cables are loose (or
broken).
There is the possibility that the compressor will not operate if the compressor
cables have been connected improperly.
Replace the cable or rewire as appropriate.
Is the wire from the SPM2 to the compressor
loose or broken, or has it been connected
improperly?
The SPM2 may be broken.
Replace the SPM2.

Is the wire from the SPM2 to the compressor
loose or broken, or has it been connected

If the unit doesnÕt work even after replacing the
SPM2, the drive circuit may be broken. Replace
the control P.W.B.
If the unit doesnÕt work even after replacing the
SPM2, the position detection circuit may be
broken. Replace the control P.W.B.
If the unit doesnÕt work even after the SPM2 is replaced, the drive circuit may be broken or
the CN14 cable may be cut. Check to see that an electrical current is flowing through the
CN14 cable.
