Technica SA GX 650 overload, overheating, fan comes on intremittently

Pulled fan continunity ckecked out, but fan is intermittent with higher out put. Is there a 'feed back' in the fan circuit that determines if fan is operating before overheating gets critical? Will replacing the fan motor fix the problem or is it deeper in the circuit?

SOURCE: I have a Technics SA-AX610 receiver that says overload .

From the manual pg 27....... "The protection circuitry has functioned because the positive and negative speaker connection wires are "shorted," speaker systems with an impedance less than the indicated rated impedance of this unit are used or under severe use, such as loud volume, excessive power and in an excessively hot environment."

SOURCE: receiver says power overload, turn system off

It probably needs soldering of the voltage regulators and/or output IC.
I think that model has an access panel on the bottom (it may need to be cut out then rotated and screwed back on when done).
If it doesn't have the panel the main circuit board needs to be taken out to access them.
The regulators and output IC are mounted on the main heat sink. a little soldering and it should be good as new.

SOURCE: Overload on Technics SA DA10

Cracked solder joints due to excessive heat cycling. Do not place in a shelf system. Top MUST be open for 1 ft. or better for proper convective cooling effect. Mine suffered same fate but repaired locally.

TROUBLE CODE CLEARING

1. Follow the diagnostic procedures to service the fault condition flashing on the air bag indicator prior to code clearing.

2. Cycle the ignition switch to OFF and then to RUN.

3. Observe air bag indicator prove-out (six ? two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.

4. Locate the Diagnostic "Trouble Code Clear" Connector (grey connector). located underneath the glove compartment, left side (06010) containing Circuits 631 (T/R) and 57 (BK).

5. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.

6. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).

7. Release short on Circuit 631 (T/R) to Circuit 57 (BK). This short must be released within 25 seconds after the diagnostic monitor tone sounds.

Diagnostic trouble code is now cleared from memory. Next highest priority diagnostic trouble code stored (if one exists) will begin flashing.

The codes and clearing proceedure above are to be used as a guide, NO claims are implied as to the correctness or accuracy of either.

Service engine light is on and code P0526


The Powertrain Control Module (PCM) uses the cooling fan speed signal in order to determine the actual fan speed in relation to the desired fan speed. The PCM uses the cooling fan speed signal in order to reduce the cooling fan noise and in order to maintain the powertrain cooling requirements. The PCM supplies power and ground to the clutch hall effect sensor of the cooling fan clutch. The hall effect sensor returns a signal pulse through the speed signal circuit in response to the reluctor track, which is located inside the fan clutch. If during operation, the PCM detects a loss of the cooling fan speed signal, DTC P0526 will set
  • An inline connector could cause an intermittent DTC. Ensure to test for poor connections and pin retention at all inline connectors. Refer to system schematics for connectors and locations.
  • If the condition is not present, refer to Testing for Intermittent and Poor Connections.
  • Disconnect the harness connector of the cooling fan clutch from the shroud. Inspect the exposed wires between the harness connector and the tubing.
  • Inspect the cooling fan clutch harness in order to ensure that the clutch supply voltage circuit is not shorted to the following circuits:
  • The 5-volt reference circuit.
  • The cooling fan speed signal circuit.
  • The low reference circuit.
  • DTC P0526 will set if the engine is started without the drive belt ON.

Hi; You still have a loose connection somewhere. I have found just recently a problem with a customer with the same problem He had burnt wiring at the compressor terminals. Also check to see if the fan on top of R.V. is running when the inside fan is running they are connected together on the same motor up top. Also check for a dirty condensor coil this can cause the compressor to fail out on thermal overload...alpharome416

Diagnostic Aids
  • Low system airflow can cause an intermittent complaint. Inspect for the following conditions:
    • Any restriction in the exhaust system that may produce back pressure
    • Pinched, kinked, restricted, or leaking pipes, hoses, or fittings
    • A restricted pump inlet hose, duct, or filter
    • Pinched, kinked, restricted, or leaking vacuum lines
    • Heat damage
  • A short to voltage in the pump relay control circuit can result in the AIR pump running continuously with the ignition OFF by back-feeding to ground. This will eventually result in pump failure.
  • An AIR pump that had become inoperative and had shown indications of having exhaust gases in the outlet port would indicate check valve failure.
  • Notice Do not operate the AIR pump for more than 60 seconds. Continuous operation of the AIR pump in excess of 60 seconds will damage the AIR pump.

    If the DTC cannot be duplicated and is determined to be intermittent, reviewing the Failure Records data can be useful in determining when the DTC was last set. Also refer to Intermittent Conditions

Intermittent F4 fault code


John , these models use a self-resetting, disc type thermal cut out in the sensor circuit. The normally open disc is wired in parallel with the sensor. When tripped, the thermal cut out shorts the sensor circuit resulting in an F4 failure code. Since you are reading the proper ohms in the sensor I believe you are ok there. They do have a kit WB24K5048 to correct this problem. The kit contains a higher rated thermal cut out, an insulation barrier and instructions. Catriver...post back.
