Cecotec Cecofry Full Inox 5500 Pro, dead, won't turn on (thermal fuse failure)
ID: 239240
Description: A very basic machine, but complicated to...
Steps:
- Short document; I am sorry I hardly have any photos of the step-by-step process. It was a repair we performed at Repair Café Palma. I helped locate the fault, but I did not perform the teardown.
- The machine was dead; it would not turn on. The power cord up to the machine's input was correct. Once the machine was opened, the sensor switch for the inserted carafe, located in the lower central part, was checked and was correct. However, from the input to the upper part, the power board, the 230 V were not reaching it.
- The first step is to remove the top cover, which is snapped into place. You must pry on the sides until you manage to release the clips; there are approximately 6 to 8 of them—I did not count them.
- Tested between the plug prong and the blue wire, NO CONTINUITY, and tested between the plug prong and the red wire, also no continuity.
- Seeing that both the red and blue wires come from the bottom, enter 2 holes in the machine toward the resistance, and then another red and blue wire come out of them and go up to the PCB, we deduce that those wires go to 2 thermal fuses, which are blown, given the difficulty of disassembling the machine and the lack of time.
- As it is a "quick" repair at Repair Café Palma, we decided not to continue disassembling the motor and propellers, and proceeded to bypass the 2 thermal fuses and connect the incoming blue and red wire directly to the PCB.
- Cut the red wire that enters the egg towards the fuse and splice it directly with a terminal block to the wire that goes up to the PCB (Red - Red).
- The machine still won't turn on, so you need to perform the same action on the blue wire.
- The same operation applies to the blue cable; it enters the opening, and another blue cable exits from it that acts as a common wire to the cooling fan, resistance, and PCB, so you have to be a bit more careful about where to cut and splice with another terminal block. Once tested, the machine's display now turns on correctly.
- A very simple machine, not designed to be repaired; it presents several problems when performing a teardown, it is "not intuitive," and to access the 2 thermal fuses that caused the failure, you have to dismantle the entire machine.
- I am sorry for not having more photos, as I did not perform the teardown and repair myself at the Repair Café Palma; I helped the colleagues locate the problem.
