Refrigeration Troubleshooting RESULTS TEST What’s done when tech arrives at home? ASK Talk to the Consumer, don’t trust the work order Talk to the Fridge, the Diagnostic Mode is the most valuable troubleshooting tool you have for troubleshooting a refrigerator. When you are at the product this MUST be the first test you should do. Removing power will erase Defrost Fault Codes, for 4-6 hours.

Compartment Temperature Sensor TESTING To show actual Temps, on older models, after checking Fault Codes (Why), power off & on. The display will show actual compartment temperature for a short time, check the actual temperature at the top rear of the compartment and compare readings. Newer models, press TEMP pad, set temp displays, then actual displays before going blank. Why could actual temp be different? (power freeze/cool, before defrost, or plugged in only a short time).
Refrigeration Troubleshooting RESULTS TEST The Forced Operation Mode is a valuable troubleshooting tool for testing compressor operation & some fan operation. Forced Freeze (FF) Mode • The compressor is started without the 5-7 minute delay You can accurately check defrost sensor voltages in this mode with the cold evaporators. You can check the compressor current draw or check voltage at the main PCB in this mode. • Some fans will be turned on in this mode, to allow voltage testing.
RESULTS Refrigeration Troubleshooting TEST The Forced Operation Mode is a valuable troubleshooting tool for testing defrost operation. Forced Defrost Mode • The Fridge (RD) defrost function can be activated (Some Models). You can check the Fridge defrost current draw or defrost voltage at the main PCB in this mode. • All defrost function & Inverter Compressors You can check All (FD) defrost current draw or All defrost voltages in this mode (All Models).
Refrigeration Troubleshooting The Forced Operation Mode “Display” Inverter compressor models will show the forced function in the display FF1, FF2, FF3, FD (all defrost). Most standard compressor models manufactured after 2007 will show the forced function in the display FF, RD, FD Most models 2006 and older will have a blank display during the forced mode, wait 5 seconds between button pushes so you know what mode you are in (FF, RD, FD). If in doubt, unplug unit and start over.

FAN MOTORS RESULT S TEST ASK DC Fan Motors Brushless DC Fan motors are used to save energy. The fans operate at two speeds. High when the ambient temperature is high and Low when the temperature is low. Generally, it is operated in the High mode during the day and in the Low at night. This circuit design is to protect the Main PCB from a failed fan motor. Fan speed information is read by the Main PCB.

Defrost Operation All new production (except RB series) uses Sheath Heaters Defrost cycle is initiated by the main PCB. 120vac is supplied to the defrost heater circuits, for the Fridge and/or for the Freezer After 90 seconds, the heaters remain on until the defrost sensor voltage tells the PCB to terminate the cycle. The PCB shuts off the heater at Sensor temps 50F in Freezer, and 63F in Fridge, after the main PCB initiates the cycle.

Defrost Troubleshooting NOTE: Evaporator Covers May Break or Crack if Removed While Frozen To Coil, replace if damaged. Ice build up in either the freezer or refrigerator compartment can be caused by a blocked drain. It is possible that the drain is not being defrosted by the heaters enough to properly clear the drain and pass the melted water into the catch pan.
Defrost Troubleshooting Metal clips “A” and “C” can be placed on both the evaporator cover and the evaporator. The metal clips will touch and transfer heat more efficiently from the defrost heaters to the drain preventing ice build up. Due to the low current draw of this heater, the foil is critical for heat transfer. Part numbers for these parts are as follows: A: DA61-03502A PLATE-DRAIN INS EVAP, REF C: DA61-03585A FIXER-EVAP REF Questions or comments? Please e-mail richard.kuemin@marcone.
Defrost Heater Replacement Out of Warranty Only The Heater Tubing is the front pass on the evaporator ass’y, it can be removed from the new ass’y and reinstalled on the one in the refrigerator compartment, after removal of the defective heater. This is for the Refrigerator side only. Extreme Caution must be used The Evaporator ass’y is very sharp and can cause injury. Note the position of the foil tape, sensor, thermal fuse, and each zip tie.
Tools required Kevlar Gloves Foil Tape Zip Ties Long Nose Pliers Cutter Drill Pop Rivet tool Heater aluminum tube is locked to the evaporator frame with two tabs on each pass. Twist each tab carefully to avoid breakage and lift up heater tubing. Questions or comments? Please e-mail richard.kuemin@marcone.

Troubleshoot Diverter Valve RESULTS TEST ASK If it fails in the all evap mode, it should work properly using slightly more energy, (possibly cooling fridge a little too much). For testing, set fridge temp warmer than the actual temp, monitor the defrost sensor(s) to see if voltage drops/temp rises. If it fails in the Freezer evap only mode, there will be a Fridge no cool Force on the Fridge with the “Pwr Cool” option. Monitor the Fridge evap(s) temp by using the Defrost Sensor(s).

Heat Release Ice Maker Ice Production & Test Explanation 38 minutes after the water fill is complete, the control board will check the temperature of the eject Thermistor, on the Ice Maker Head. If the Thermistor reads a temperature lower than 18.5 degrees for more than 5 seconds, the Ice maker will harvest if the ice bucket is not sensed as full. Press and hold the ICE TEST S/W for at least 1.5sec, the harvest function will start. The Ice maker heater turns on for 30 seconds to 2 minutes.

Service Concerns Flex Tray I/M Shattered Ice Cubes When all ice shatters it's because of a bad tray or harvesting at a temp that is too cold (lower than 1.5 degrees), in some areas there are water issues that can also cause shattered cubes. The temp in the freezer should not have any effect on this issue, as long as it’s below 1.5 degrees, as a properly installed sensor will not read the freezer temp, only the water/ice temp. Check the Ice tray for defects in the plastic.
