Most modern housewives know firsthand about the benefits and effectiveness of Redmond multicooker. This multifunctional kitchen fixture has provided thousands of homes with wholesome, nutritious, hot, and delicious food. Everyone who has used this device at least once has become convinced of its effectiveness. However, like all electrical appliances, it is subject to various breakdowns. First of all, failures in the operation of the device are attributed to a factory defect. Nevertheless, it sometimes happens that the device breaks down during operation. It is then that most people think about repairing a multicooker with their own hands. It is possible to perform it at home, but for this you will have to take into account several nuances.
Operation requirements
In order to protect the Redmond multicooker from breakdowns and not think about how to fix it with your own hands, you must comply with the requirements prescribed in the device manual.
The first step is to highlight the sequence of stacking products before cooking. Remove the food bowl from the Redmond multicooker before placing it. Otherwise:
- liquids poured into the bowl, through negligence, can spill inside the mechanism;
- forgetting that the container is on the table, you can start pouring liquid into the inside of the equipment, thereby drowning the mechanisms or filling them with bulk products.

Common causes of failure of Redmond multicooker
Most malfunctions occur due to contamination of the device contacts. This can be caused by the ingress of liquids or loose products into the interior of the device, such as:
- cereals (rice, buckwheat);
- sugar;
- salt.
This type of breakdown is the most harmless and it will be easy to repair the multicooker with your own hands. At the same time, it is worth remembering that until the end of the cleaning and assembly process of the structure, the device should in no case be connected to the network.

How to clean a Redmond multicooker?
To clean the device with your own hands, it is important to study and follow the sequence of actions.
- Remove the metal (plastic) cover and other visible items attached with screws.
- Clean the microcircuits by turning the device over and gently shaking it off.
- Secure the cover and other top elements.
If the clogged contacts are at the bottom of the device, you must:
- unscrew the screws securing the bottom cover;
- disconnect the cables connecting the heating and software boards;
- remove the heating element by unscrewing the screws;
- carefully remove the internal thermometer without damaging the device;
- clean chips and boards from loose products.
Observing the rules of disassembly, cleaning the device will not cause much trouble.

Redmond multicooker software errors
In some cases, Redmond multicooker may stop working, displaying a specific alphanumeric error code. The ability to decipher the code will allow you to understand the cause of the breakdown and start fixing it. The information for decryption is known to manufacturers, as well as to craftsmen specializing in the repair of household appliances.
Certain errors displayed on the screen indicate serious malfunctions. Nevertheless, there is a list of codes explored by ordinary users through trial and error.
Thus, craftsmen managed to find out that the message "e0-e4" displayed on the screen signals faults associated with short circuits, as well as breaks of temperature sensors located above or below. Also, the problem may be related to thermal fuses. Various manufacturers set their own codes, so for repairs on your own, you will need to remove the device case and use the capabilities of the multimeter to detect an open by measuring the level of contact resistance.
Another common reason that a multicooker may need to be repaired is a clogged thermal relay responsible for heating. In most cases, it is located at the bottom of the device, next to the power board. To get to and repair the thermal relay, you need to remove the bottom of the structure. Before cleaning, the copper contacts must be slightly unclenched, and then wiped with zero emery cloth or thick paper. The reason for such a breakdown may be the accumulation of moisture that has penetrated into the mechanism due to the liquid spilled past the bowl. Condensation is also possible.

What is the function of a thermal fuse?
A thermal cutout for a multicooker is one of its most important parts. It is a small piece of wire that is indistinguishable from a resistor. The conductivity index is 10-15 A, based on the type of element. The highest temperature is 150-170 degrees. Exceeding the permissible limits will lead to a blown fuse and an open circuit, which can be determined using a multimeter.
Finding and replacing a thermal fuse
The most important part of the Redmond multicooker is at the center of the device. Most modern models are equipped with several thermal fuses covered with protective plastic insulation. To detect a blown fuse, you must dismantle the bottom cover of the device.
After removing the bowl, you can see the button: outwardly, the assembly resembles a steel mushroom, the lower part of which is covered with a spring. The circumferential surface is the heating element of the Redmond multicooker. Thermal fuses are located near the main unit.
In this case, the plastic insulation is visible. Some manufacturers secure them with clamps screwed to a screw, but in most cases, the fuses simply dangle in the air.
Since the factory fastening of the fuses is performed by crimping, the use of soldering is strictly prohibited, since a red-hot soldering iron can burn out the heat-sensitive fuse. To determine which particular element is defective, and also whether at least one of them is working, use a multimeter to measure the resistance without removing the fuse. After finding a fault, the fuse must be replaced.

Microcircuits in modern multicooker Redmond
Modern multicooker is equipped with two electronic boards:
- managers;
- power.
The main board, responsible for heating, is located at the bottom of the device, while the control board is located in the heart of the device - inside the working cylinder.

A close inspection of the microcircuits reveals several signs of problems:
- delamination of tracks;
- violation of solder seams;
- blackening of resistors;
- swelling of capacitors;
- formation of carbon deposits.
If one of the items on the list is found, it is worth repairing or replacing parts, restoring the soldering or tracks of the board using a zero skin and tinning the damaged places. Jumpers can be made from burnt-out resistors using their legs. To secure the soldering and tracks, it is recommended to use a varnish that protects the circuit from leaks and oxidation.
