Most modern housewives know firsthand the benefits and effectiveness of Redmond crock-pots. This multi-functional kitchen appliance has provided thousands of homes with healthy, nutritious, hot and tasty food. Everyone who at least once used this device, in fact, was convinced of its effectiveness. However, like all electrical appliances, it is subject to various breakdowns. The first thing the device malfunctions is attributed to a factory defect. However, sometimes it happens that the device breaks down during operation. That's when 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.
Operating requirements
In order to protect the Redmond multicooker from breakdowns and not think about how to fix it with your own hands, you must follow the requirements prescribed in the device instructions.
The first step is to highlight the sequence of laying products before cooking. Before stacking, the food bowl must be removed from the Redmond multicooker. Otherwise:
- liquids poured into the bowl, through negligence, can spill into 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 Redmond Multicooker Breakdowns
Most malfunctions occur due to contamination of the device contacts. This can result in liquids or bulk products entering the inside 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 multicookers with your own hands. It is worth remembering that before the end of the cleaning process and assembly of the structure, the device must in no case be connected to the network.

How to clean a Redmond slow cooker?
To clean the device with your own hands, it is important to study and follow the sequence of actions.
- Remove the metal (plastic) cover, as well as other elements that are in sight, attached with screws.
- Clean the chips by turning the instrument over and gently brushing it off.
- Fasten the cover and other upper elements.
In case clogged contacts are located 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.
Following the rules of disassembly, cleaning the device will not cause much trouble.

Redmond Multicooker Software Errors
In some cases, Redmond multicookers may stop working by generating a specific alphanumeric error code. The ability to decrypt the code will allow you to understand the cause of the breakdown and begin to eliminate it. Information for decryption is known to manufacturers, as well as to masters specializing in the repair of household appliances.
Certain errors displayed on the screen signal serious malfunctions. Nevertheless, there is a list of codes that are 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 in 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’s case and using the capabilities of the multimeter to detect an open circuit by measuring the level of contact resistance.
Another common reason that may require the repair of multicookers is the clogging of the thermal relay responsible for heating. In most cases, it is located at the bottom of the device, next to the power board. To get and repair the thermal relay, it is necessary to remove the bottom of the structure. Before cleaning, the copper contacts need to be unclenched a little, and then wiped them with a zero emery cloth or thick paper. The cause of such a breakdown may be the accumulation of moisture that has penetrated into the mechanism due to liquid spilled past the bowl. The formation of condensate is not excluded.

What function does the thermal fuse perform?
A thermal fuse for a multicooker is one of its most important parts. It is a small piece of wire 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 norms will lead to the burning of the fuse and rupture of the electrical circuit, which can be determined using a multimeter.
Search and replacement of thermal fuse
The most important part of the Redmond multicooker is in the center of the device. Most modern models are equipped with several thermal fuses covered with protective plastic insulation. To detect a blown fuse, remove the bottom cover of the device.
After removing the bowl, you can see the button: externally, the knot resembles a steel mushroom, the lower part of which is covered with a spring. The surrounding 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 fasten them with clamps screwed to the screw, but in most cases, the fuses simply hang in the air.
Since the fuses are factory crimped, the use of soldering is strictly forbidden, since a hot soldering iron can burn a heat-sensitive fuse. To determine which particular element is faulty, and even if at least one of them works, use a multimeter to measure the resistance without removing the fuse. After a fault is detected, the fuse must be replaced.

Chips in modern multicookers 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 at 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.
