System TroubleShooting Problem What Could Be Wrong How To Fix The System motor will not turn on. NOTE: the float switch directly cuts power to the motor when the liquid gets low. Use float jumper to diagnose any float issues. Insecticide level is to low. Float is down Refill insecticide reservoir. Float switch (inside the reservoir) is stuck in a downward position. Release float from stuck position. And/or shake float bulb to see if it is possible internally stuck Digital timer makes a single snapping noise when cycle activates, but motor does not run The snapping means power is being sent to the onboard relay, but not getting to the motor. The float is the only interrupt in between the timer and the motor. Float could be stuck or float could be defective. Use jumper plug to diagnose. Possible replacement of float could be needed. Analog clock timer keeps time, but does not operate the System at preset times. Manual button WORKS. Possible 24 hour clock problem Replacement of 24 hour clock may be needed Analog clock timer keeps time, but does not operate the System at preset times. Manual button DOES NOT work. Possible internal interval/relay problem Replacement of may be needed interval/relay Analog timer runs continuously and will not shut off unless unplugged Possible internal relay contacts sticking Replacement of may be needed interval/relay Contacts in potentiometer (seconds knob) are bad. Replace potentiometer. Problem What Could Be Wrong How To Fix Digital timer does not keep time or program in memory when power is lost. NOTE: Replace batteries once per year. On board AA batteries are low on power/dead. Remove front display panel to access black AA battery case. Replace AA batteries. Perform “reset to defaults” Reprogram timer. Digital timer has odd reading on display, but works via manual button (up). On board AA batteries could be low on power/dead or could need to perform “reset to defaults”. Replace AA batteries (see previous page) and/or perform “reset to defaults”. Digital timer has no display reading, will not perform any functions. Display/logic board may be corroded or malfunctioning. Replace LCD/Logic board. Digital timer has no display reading, but programming and manual functions work. The display is LCD and has lost visibility under extreme heat. Relocate system reservoir and pumping unit to area out of direct sunlight or indoors (garage or shed). Digital timer will only activate via manual button (up) or with remote control. NOTE: a “reset to defaults” can help to cure this if all else fails. Timer is in manual mode. LCD screen reads “off” Push the down keypad button so LCD screen reads “on”. Button on keypad could be defective or keypad cable could be cracked. Replace keypad. Digital timer performs all functions but remote control does not work. Battery in remote control is dead. Open remote control and replace battery. Older remotes will need to be reprogrammed to the timer. The System operates at normal pressure, but nozzles do not spray. Nozzle tips may be clogged with debris. Clean or replace nozzle tips. Filter water when filling to minimize clogging problems. Tubing could be kinked not allowing liquid to get to nozzles. Unbend or unkink tubing. Gauge could be defective and giving an incorrect (lower) reading. Replace gauge. Inline filter could be clogged. If system has an inline filter, check to see if it is clogged and needs cleaning. Filter should be located in the outgoing feed line after the pump. Problem The System operates, but has low or no pressure. The pump/motor surges on - off, on - off. The system is tripping a circuit breaker. What Could Be Wrong How To Fix Pump may be defective. Unplug system. Remove pump from motor, spin shaft on pumpwith fingers. Shaft should spin freely, if tight, replace pump. Needle valve fitting on pump is in an outward position, bypassing liquid back into reservoir.. Turn screw on needle valve fitting in, clockwise, until pressure reads 170-180 psi on gauge. Needle valve fitting on pump is defective and not allowing pressure to build. Replace needle valve fitting on pump Suction filter (inside of reservoir) is plugged with debris. Remove suction filter, clean or replace. Air leak on the suction fitting (elbow) on the pump. Check fittings, secure tubing into suction fitting making sure it is properly seated. Check valve before suction filter in reservoir is malfunctioning. Remove check valve from tubing and run system briefly to check. Replace check valve. Tubing has a leak, cut or break. Look for leak, use union to slice in or replace tubing. Needle valve fitting on pump is screwed in to far. Motor will heat up from this and cause to thermally shut off. Turn screw on needle valve fitting out, counter-clockwise, until pressure reads 170-180 psi on gauge. If motor is hot and will not run, let it cool down and the thermal overload will reset. The reservoir liquid may be low and the return liquid is spraying onto the black float bulb. Reposition the return line so that the liquid is not spraying onto the black float bulb. Refill the system. . The motor may be defective. 706-742-2151 www.autoflyspraysystems.com Unplug system. Remove pump from motor, spin shaft of motor with fingers. Shaft should spin freely, if tight, replace motor. And/or run motor without pump attached to see if the motor runs tough, makes noise or heat up. Replace motor if any of these symptoms occur.
