5. COLD AIR FLOW SCHEMATIC DIAGRAM The cold air generated in the evaporator is forced into the freezer compartment and into the refrigerator compartment by the motofan. In the freezer compartment the cold air is distributed through the top flow to the shelves and the food is frozen by the cold air flow.
6. OPERATION The DF36 Electromechanical Frost Free refrigerator works under the vapor compression cycle R134-a. The vapor is compressed in the alternate compressor, release heath in the condenser, is restricted into the capillary pipe and absorbs heath in the flap tube evaporator, returning to the compressor as vapor through the suction line.
6.1.2 Defrost Bimetal registering a temperature less than -6ºC (±4ºC) when the refrigerator is turned on (in the case of a power failure happening before the product has achieved a temperature above +25ºC (3 ºC) in the defrost bimetal). Accumulates 8 hours, considering the time accumulated befor the turn off Pause (10min) (dripping with the resistances already turned off) Defrost (up to +25ºC in the Bimetal) 6.1.

PRODUCT DISASSEMBLING 2.1 Access to the Freezer Components 2.1.
2.1.5 Pull the cover as shown in the image below and disconnect the motofan. 2.1.6 Disconnect the motofan thermostat – it has a locking connector that should be pressed so as to be released. Note.: The removal of this cover can be hindered if the product is cold since then the ice can stuck it to the evaporator. Await a few minutes to remove the cover. 2.1.
2.3 Removal of the Top Flow Assemblage To remove the top flow assemblage located on the top of the refrigerator compartment, you should remove the two Phillips screws and carefully loose the assemblage from its supports in the back of the internal box. To finally remove the assemblage, unplug the six ways connector releasing its security lock. 2.
2.5 Removal of the Thermostat Remove the air duct and pull the thermostat button out of the top flow. Release the thermostat from the fasteners that hold its body and spiral bulbous from the top flow casing. This document cannot be reproduced or passed to third parties without authorization of Electrolux do Brasil S.A.
Note: when replacing the thermostat by a new one, please pay attention to the bulbous fastening to the vertical groove on the top flow cover, locking the spiral bulbous in the casing. Attention: do not remove the plastic coat that covers the bulbous. 2.5.1 To replace the gutter resistance with the internal net, detach the ribbon that fixes the net to the air duct and release the top flow internal net from the fasteners.
2.6 Disassembling of the Door Handle 2.6.1 With the help of a screwdriver, remove the handle cover applying pressure from below so as not to scratch the surface. Pull the cover to the front, releasing it. 2.6.2 With the help of a Torx T30 tool, remove the screw and release the handle pulling it to the left to release the lock, and then to the front. 2.6.3 To assemble the door handle, please follow the same sequence previously described backwards.
2.8 Replacement of the Motofan 2.8.1 Follow the procedure described in item 2.1, Access to the Freezer Components. 2.8.2 With a cutting pliers, cut the fasteners that fix the motofan net on the evaporator cover. 2.8.3 With a needle-nose pliers, remove the propeller lock so as to release the propeller. 2.8.4 Remove the Phillips screw from the motofan cover and, with the help of a screwdriver, release the locks. 2.8.5 Remove the motofan motor.
2.9 Disassembling of the Evaporator (bimetal, thermal fuse and defrost resistance replacement) Evaporator Replacement (procedure for products outside the warranty period) 2.9.1 Follow the procedure described in item 2.1, Access to the Freezer Components. 2.9.2 Loosen the two Phillips screws that fix the evaporator to the internal box. Attention: Be careful not to drop the screws in the gutter bellow the evaporator or in the damper duct.
2.9.10 To remove the Reflecting Gutter: • Unplug the connectors of the fuse-bimetal circuit and the resistance. • Pull the evaporator locks to release the reflecting gutter. 2.9.11 To replace the fuse-bimetal circuit: • Carefully turn the evaporator from the right to the left, as shown in the picture bellow. • Using a cutting pliers, remove the four plastic fasteners that fix the fuse-bimetal circuit to the evaporator.
2.9.12 To replace the defrost resistance: • Release the metal fastener that fixes the resistance under the evaporator. • Release the resistance from the evaporator fittings. To install a new resistance, fit it in the evaporator fittings and then fix it with the metal fastener. 2.10 Removal of the Timer 2.10.1 With the help of a Phillips screwdriver, loosen the screw that fixes the box which contains the timer. 2.10.2 Carefully remove the box, unfitting it from the internal lateral side of the cabinet. 2.

CONTENTS 1. TESTING PROCEDURES ......................................................................................................................... 1.1 How to know if the board is energized ............................................................................................... 1.2 Operation of the compressor and motofan ......................................................................................... 1.3 Operation of the bulbs ............................................................
1. TESTING PROCEDURES 1.1 How to know if the board is energized With the help of the digital multimeter, measure the alternate tension (127V or 220V) between the brown and blue wire terminals of the compressor, as indicated in the scheme below: 1.2 Operation of the compressor and motofan The control of the operation of the compressor and the motofan is done by the thermostat and timer.
1.3 Operation of the bulbs To verify the proper operation of the bulb, measure the alternate tension (127V or 220V) between the terminal 1 of the thermostat and the terminal 4 of the multi-way connector of the refrigerator top flow. ! Thermostat test With the thermostat in the turned on position, it should have been continuity between the terminals 1 and 3. If there is no continuity, the thermostat must be replaced.
1.4 Operation of the defrost system To check the operation of the product defrost system the steps bellow should be followed: 1.4.1 Forced Defrost With the help of a screwdriver, turn the timer mechanism in the clockwise sense until you hear the first click, so as to manually advance it to the defrost position. At this point, a change occurs in the timer contacts going from 1-4 to 1-2, turning off the product compressor. 1.4.
! Gutter Resistance In the multi-way connector, located in the refrigerator top flow, it is possible to measure the ohmic resistance the tension of the current being fed to the gutter resistance. 1. In the refrigerator top flow male connector, measure the value of the ohmic resistance of the gutter resistance positioning the probing needles of the multimeter, already set to the resistance scale, on the terminals 5-6.
2. ELECTRICAL COMPONENTS TESTING PROCEDURES 2.1 Compressor Measure the terminals (C, S e R) with the digital multimeter set to the lesser scale of ohmic resistance, with the compressor at 25ºC. 127V/60Hz 220V/50-60Hz Between R and C 2,8 10,35 Between S and C 7,1 43,1 Between S and R 9,9 approx. 53,5 approx. 2.2 Thermostat Measure, with the help of the digital multimeter set to the continuity scale, the thermostat disconnected from the mains.
2.3 Timer With the timer disconnected from the mains, measure with the help of the digital multimeter set to the continuity scale. Turn the timer cam with the help of a screwdriver until hearing the first click and then measure. Timer at defrost Timer turning on the compressor / motofan There is continuity between pins 1 and 2. There is no continuity between pins 1 and 4. Turn the timer cam with the help of a screwdriver until hearing the first click and then measure.
Switch with the freezer door open. Switch with the refrigerator door open. SWITCH SWITCH There is continuity between pins 1 and 2. There is no continuity between pins 1 and 3, 1 and 4. There is continuity between pins 1 and 4. There is no continuity between pins 1 and 3, 1 and 2. 2.
