Why is my Micro Matic MMPP4302-R Power Pack dispensing excessive foam?
Excessive foam can be caused by several factors. First, ensure your walk-in cooler is set between 36° to 38°F using a quality thermometer. Next, check the pressure applied to the keg and adjust the regulator for a proper flow rate of two (2) ounces per second. Also, examine the physical equipment from the keg to the faucet. Warm product lines can also cause excessive foam.
What to do if Micro Matic MMPP4302-R compressor doesn't start (no hum), but the fan motor runs?
If the compressor isn't starting but the fan motor is running, the issue might stem from a compressor relay or capacitor malfunction, in which case you should replace the compressor relay or capacitor. Another potential cause is inadequate voltage. Measure the voltage across the common and run terminals on the compressor; the voltage must not drop below 90% of the rated voltage. If neither of these resolves the issue, the compressor itself may have failed and require replacement.
What to do if Micro Matic MMPP4302-R Power Pack compressor does not run but hums?
If the compressor hums but doesn't run, first measure the voltage across the common and run terminals; it should not drop below 90% of the rated voltage. If voltage is adequate, the starting relay may be malfunctioning and needs replacement. Ensure you use the correct relay, as using the wrong one can cause compressor failure. If these steps don't solve the problem, the compressor itself may be malfunctioning and require replacement.
Why does my Micro Matic MMPP4302-R Power Pack compressor run continuously and freeze up?
A compressor that runs continuously and freezes up could be due to a thermostat control failure, requiring thermostat replacement. Alternatively, there may be a freon leak that needs to be repaired and the system recharged.
What to do if my Micro Matic Power Pack is dispensing warm beer?
If your beer is warm, consider these potential causes: * Check the pump. Look for liquid flow in the return line of the reservoir. Replace the pump on 125’, 250’, and 500’ units, and inspect the motor, checking the condition of the key between the pump and motor. * Replace a defective motor (check pump also). * Remove trunk lines from any hot water pipes or kitchen areas with stoves or glass washers if they are located in overheated areas. * If trunk lines are flooded in a PVC chase, remove the lines, thoroughly dry the PVC, and repair or replace the trunk line as needed. * Ensure all lines are fully insulated from the cooler to the dispenser, including glycol lines from the power pack to the cooler. * Adjust the thermostat to a colder setting. * Replace the condenser fan m...
