How to replace the heating tube of the electric oven?
An electric oven is an electric heating appliance that uses the radiant heat emitted by an electric heating element to bake food. Using it, we can make roast chicken, roast duck, bake bread, cakes, etc. According to the different needs of baked goods, the temperature of the electric oven can generally be adjusted within the range of 50-250°C.
The electric oven is mainly composed of a cabinet, an electric heating element, a thermostat, a timer, and a power adjustment switch. The box body is mainly composed of a three-layer structure of an outer shell, a middle compartment and an inner liner. The front and rear sides of the inner liner are formed with curling to block the air in the cavity; the outer cavity is filled with insulating expanded perlite products to make the outer shell The temperature is greatly reduced; at the same time, a spring structure is installed under the door, so that the door is always pressed on the door frame, so that it has a better seal.
When the oven does not heat up normally, it is possible that the built-in electric heating tube is broken and needs to be replaced. The specific steps are as follows:
1. Unplug the oven and disconnect the power.
2. Remove the panel covering the heating element. Due to the differences in the design of different oven products, the disassembly method of the metal plate covering the electric heating tube may be different. Generally, it is at the bottom of the oven. There are some card slots on the edge, which can be pulled up with a little force.
3. Remove the electric heating tube. Use a screwdriver to unscrew and pull out the screws at each connection part. Most heating tubes have 2 screws on the bottom and 2 screws on the back.
4. Separate the connected wires. The electric heating tube is connected to the oven with wires, so be careful not to damage other components when disassembling.
5. Determine the specifications of the electric heating tube that needs to be replaced. If there are specifications and models on the product, please purchase a new electric heating tube according to this specification. If not, you need to measure the diameter of the electric heating tube and calculate the power of the heating tube.
6. Install a new electric heating tube
