NORMALLY CLOSED NORMALLY OPEN 12 − 58 Troubleshooting 12−FAN CLUTCHES Normally Closed Fan Clutches Problem Possible Cause Solution Fan won't engage when manual override is turned on. Manual override switch, air solenoid valve or related plumbing or wiring is faulty. Replace faulty component. Fan won't cycle on when air Outside air temperature is too low, there is a conditioning test is performed. low refrigerant charge or refrigerant pressure switch is faulty. Overtemp warning activates before fan engages. Engine appears to overheat. (Fan won't engage when engine coolant temp gauge is above 195−205°F or overtemp warning activates before fan engages.) Defective overtemp warning switch. 1. Air Solenoid valve may be plumbed incorrectly 2. Overtemp warning switch faulty (warning light activates prematurely). 3. Overtemp warning switch is too far away from the fan temp switch. 4. Temp gauge is faulty (reads high). 5. Fan temp switch is faulty. 1. Check air conditioning system. 2. Replace pressure switch if required. Replace overtemp warning switch. 1. Check solenoid plumbing. Replumb solenoid valve. 2. Replace overtemp warning switch. 3. Move overtemp warning switch as close to the fan temp switch as possible. 4. Replace temp gauge. 5. Replace fan temp switch. Fan engages at low engine temperatures while vehicle is moving. 1. Normal condition in extremely hot weather or at slow vehicle speeds in warm weather. 2. Faulty temp gauge. 3. A/C system overcharged or condenser covered with debris. 4. Refrigerant pressure switch may be faulty. 5. Fan temp switch is faulty, if fan engages at low engine temp and A/C is OFF. Fan won't run under any condition. 1. Air line may be leaking (Horton/Evans air−on fan drives). 2. Wiring may be shorted and/or fuses, circuit breakers blown. 3. Air solenoid may be faulty. Test air solenoid valve by shorting across the terminals of the temp switch to energize the air solenoid valve and to activate the fan drive. 1. Normal condition in hot weather. 2. Replace temp gauge or sender. 3. Check A/C system. 4. Replace pressure switch if necessary. 5. Replace fan temp switch. 1. Check air lines. Fix where necessary. 2. Check wiring, fuses, and circuit breakers. 3. If solenoid does not activate, replace solenoid. 12 − 59 12−FAN CLUTCHES Troubleshooting Normally Closed Fan Clutches Problem Fan runs all the time when the air conditioning is OFF. Possible Cause 1. Manual override switch is ON. 2. Air solenoid valve may be faulty or plumbed incorrectly. 3. Air line to clutch may be leaking (Bendix/Kysor air−off fan drives). 4. Fan temp switch may be stuck open; with engine temp below 180°F short across terminals, if fan turns off, switch is faulty. 5. Pressure switch may be stuck open; turn off A/C system, if fan continues to run, short across pressure switch, if fan stops, pressure switch is defective. Fan runs all the time when the air conditioning is ON. Solution 1. Turn manual override off. 2. Check air solenoid valve plumbing, replace valve if faulty. 3. Check air lines, fix where necessary. 4. Replace fan temp switch. 5. Replace pressure switch. 1. This is a normal condition in extremely hot weather; spray water on A/C condenser (fan should disengage for a short period of time and then re−engage after water evaporates). 2. Air conditioning system may be over−charged or condenser covered with debris. Turn OFF the A/C system; if the fan stops, the refrigerant pressure switch is functioning. 3. Pressure switch may have drifted out of calibration; use pressure gauge to compare actual fan−on and fan−off pressures vs. specified pressures. 1. Normal condition in hot weather. 1. Loose electrical connection. 1. Check wiring; fix where necessary. 2. If other system components and connections check out okay, (a) replace pressure switch if erratic fan operation is associated with air conditioning at idle or (b) replace fan temp switch if the erratic operation occurs primarily when the engine is hot. 2. Service A/C system. Check A/C pressure and condenser. 3. If out of calibration, replace pressure switch. Fan operation is erratic. 2. Fan temp or pressure switch may be faulty. Fan cycles frequently when engine is hot. 12 − 60 The fan should remain engaged long enough to reduce temperature 7−10єF. The fan temp switch is defective if the fan disengages after only a 3−4є reduction. Replace fan temp switch. Troubleshooting 12−FAN CLUTCHES Normally Closed Fan Clutches Problem Possible Cause Solution Fan cycles frequently when vehicle is stationary with A/C ON. Up to 4 cycles per minute is a normal condition for conventional control systems; turn off air conditioning system and cycling should stop. To reduce cycling by up to 90%, install an Index K7 fan control system. Fan turns on whenever ignition is on (turns off when engine gets hot). Air solenoid valve plumbed backwards. Check solenoid installation instructions; plumb correctly. Control system fuses blown. 1. If fuse blows whenever the ignition is turned on, the problem is most likely related to a fault in the wiring. 2. If the fuses blow only when the fan engages, the fault is probably associated with the solenoid valve. 1. Check wiring, fix where necessary. 2. Use an ohmmeter to check for a shorted solenoid coil (the coil resistance should be greater than 14 ohms). If shorted, replace air solenoid valve. 12 − 61 12−FAN CLUTCHES Troubleshooting Normally Open Fan Clutches Problem Possible Cause Solution Fan won't engage when manual override is turned on.
