Repair commercial Panasonic oven to solve abnormal heating problems

Repair commercial Panasonic oven to solve abnormal heating problems

For hotel restaurants or bakeries, ovens are frequently used, and a common fault caused by Hong Kong Junhong Electrical Repair Center during repairs is abnormal heating, which results in poor taste of bread and pastries. Like when I repaired a commercial Panasonic oven before, it was to solve the abnormal heating problem. Next, I will share the operation process in detail.

1. Why does the commercial oven heat up too slowly?

The problem encountered when repairing commercial Panasonic ovens before was that the heating was too slow. The pastry chef set the preheating temperature in the morning and went to do other preparations. As a result, the oven problem did not meet expectations at the preset time. Here in Hong Kong Junhong Electrical Appliance Repair Center will immediately dispatch technicians to your home for repairs. The repair methods are as follows.

(1) When repairing a commercial Panasonic oven, first check the power supply voltage to confirm that the power supply and power cord are not damaged or abnormal, then disassemble the casing and use a multimeter to continue checking the equipment circuitry to confirm that there is no open circuit.

(2) After confirming that there are no abnormalities in the circuit, check the core heating components. Because this Panasonic oven only heats slowly, there is a high probability that it is not a problem with the heating components. After checking, there is no abnormality in the heating capacity of the heating components.

(3) Afterwards, the console shell was disassembled and measured with a multimeter. It was found that the temperature control motherboard under the console had poor contact, which caused intermittent heating of the oven. So the maintenance personnel replaced the faulty heating host. plate.

2. Uneven heating of commercial convection ovens

What I shared before was a case of repairing a commercial Panasonic oven, and there were cases of abnormal temperature in the oven and uneven heating. This phenomenon mainly occurs in convection ovens. The convection oven refers to the heating fan that circulates heat to achieve rapid heating. Next, let’s talk about how to troubleshoot and solve the problem of uneven heating in commercial convection ovens.

(1) As mentioned earlier, the convection oven mainly uses a heating fan to achieve hot air circulation and increase the heating speed. Therefore, if the heating is uneven, check the fan first. The Midea convection oven I encountered before had abnormal noise from the fan. After disassembly, I found that the fan blades were seriously aged, so I replaced the fan blades with new ones and the problem was fixed.

(2) For commercial oven heating problems, the heating components and console should also be checked. The inspection method is also to conduct tests and use a multimeter to troubleshoot faults and find open circuit areas.

For example, in the case of repairing a commercial Panasonic oven just mentioned, the user needs to pay attention to the problem of abnormal heating of the oven. The oven itself has a heating and power-off protection function, so if it encounters an abnormality, it must be paid attention to and reported for repair in time.
