Good evening, Mr. Colleagues. My question is this; I am an expert in microwave oven repair. My intention is to provide a diagram so that they can put together a tool to check microwave ovens. Is it so kind in which section can I publish it? Beforehand thank you very much. Luis Alfonso Galindo. From Bogota Colombia.

16864935_1214270738688308_8082717607515793700_n.jpg [35.16kb] cordial greetings to all colleagues Members de (YoReparo) Wishing you the best of success for this new Year 2018. Well promised is debt. My purpose is to provide you with this means, a diagram to develop a Titled Tool (Series Focus Ammeter) First It has the function of detecting failures at the time that an electronic circuit, / Electric presents a short circuit fault, in this case the bulb focus it will illuminate at full intensity indicating that some Circuit is in Short Circuit. The function of the Ammeter is to measure the Consumption in current registered in Ammeter, Example "We have the case of a Microwave Oven" That is in good working condition, We connect it to the current of consumption of the tool, we give a timing to say ; of 60 seconds, in this case in the cavity there must be a heat resistant container with water. Bearing in mind that ovens cannot be started empty. Well based on these principles we proceed to start in the first seconds the (((AMP))) Registers an approximate primary load of 5 Amps then establishes its total consumption for say 10 AMP This is according to the consumption of each device, The Repair Technician It should be noted that the measure has no intermittence (((MUST STAY FIXED THE MEASURE))) If you notice intermittence in the Ammeter, we have problems with the Appliance under Review In the case of the Washers if I have noticed oscillatory changes that are normal. Well that is my tool that I designed several years ago. My wish is that the Armen and put it into operation. Another Example: "It turns out that a Repairer is going to fulfill an address" simply between the suitcase he carries his Multimeter and some screwdrivers. "And at the time of the review the Microwave Oven starts turning the plate, the fan is heard but does not heat" As would make to give a reliable diagnosis! Good that at your service your questions.

Luis. I have some doubts about the operation of your tool, but in order to solve these, I will say them one by one ..... The first one, it is possible that the oven operates with an incandescent light bulb at 100 W, being connected the section of High Voltage ,, once you have selected x time and give start order or Start ?? Regards

Cordial greeting CESAR ALEX. As for your question; "" (((, it is possible that the oven operates with an incandescent light bulb at 100 W, the High Voltage section being connected, once time has been selected and giving a start order or Start! Greetings! ¡¡¡)))) No, you can start taking into account that the consumption of a Microwave Oven is in the order of 10 15 Amps. We will assume that an Oven arrives at the workshop Off, in the review we find Open Fuse, in There are many doubts at that moment ... as for example; some circuit is short. We proceed to disconnect the two ...

High-voltage transformer primary wires, and instead of them we proceed to "Feed it" With the output of the Bulb light bulb series if the bulb is turned on at full intensity we are in the presence of a possible cross element. The same is true for high voltage diode tests, the spotlight is illuminated at medium voltage, in the high capacitor it should not be illuminated at all, at the time of the test, the aforementioned does not charge, considering that it is alternating current. For tests of Control Panels, if everything is OK, the Display should light up. Regards...

Perfect, Luis! I still had certain questions that have been discarded thanks to your written explanation and the video of your authorship. And I only have this one: What would happen to the tool (focus behavior and ammeter) if one of the magnetron terminals (F or FA) was grounded? It is clear that among them there is a very low value in ohms but between these and the magnetron's body or metal body the reading is infinite ...

Luis: I don't know if he thought I'm "teasing you" or that I'm kidding. Maybe I should rephrase the question ... I am clear that in the presence of a short circuit, the voltage drops, but the current consumption (amps) increases and this would blow the fuse ..
Until now, I have not seen a damaged magnetron open the main (ceramic) fuse. The only elements that melt it are the capacitor and the high voltage transformer, not forgetting that the SW MONITOR also does it. Also the VARISTOR .. Regards

So far, I do not read that you have published the manual or tool for microwave oven repair .. If you wish, you can place your tool and how it is used, in this, your own theme. We will take care that your name appears as who has developed the project. Greetings to Colombia !!!!

The tool is protected with fuse of 15 Amps this in order that if it surpasses current it is protected. Well, what I want is that, whoever can make it and take advantage of it. The use is very easy to use as I had explained in the Video, the oven is first checked by means of the Bombillo bulb after everything is ok, we proceed to connect it to the power outlet that is to say the one that is in series with the Ammeter , and from that moment the conclusions of good functioning, consumption ETC. I also tell you that approximately during the year ...

it is repaired ... approximately 1000 furnaces work for companies where there are up to 15 devices in operation, even electrical installations have been designed, with Ammeters giving good results since the maintenance operator can draw conclusions from those mentioned in operation. As soon as repairs have been seen everything, with quite curious failures. for example; an oven that went through several workshops without any solutions. Upon arriving at our service workshop WITH OPEN FUSE. We proceeded to investigate first that everything were the procedures

Review, fortunately in the last workshop the one who reviewed it was a Student Colleague who passed through my knowledge classrooms in the year 93. He told me that when he checked it he found that everything was in an apparent state of operation. I even change the most suspicious. However, based on these principles, it was installed in the Tool recording the (2) Start times after a few minutes the Ammeter began to register flashes ("Notifying that any component is about to fail") and immediately shuts down! at abrupt change of the Ammeter It is detected short ...

in my Smells it came to something, it was overheating at a considerable temperature! My focus was on the components that are most heated (((Magnetron Thermal Fuses))) And I must look closely at the Thermal Fuses especially the one installed above the Magnetron, I was over temperature, in its measurement record in condition Open for a "supposedly" effective test, of course it is understood that the thermal is in an open temperature condition. That's right. But the abrupt change of the ammeter? It turns out that the thermal fuse has a very large measurement

Interesting; It is measured in (3) states. The first (1) in Cold condition (2) Hot Condition. (3) The most important to measure >>> Contact terminals, and Metal body <<< In the aforementioned case of the Microwave oven, thermal was found in Open condition when it was hot, and crossed between contacts and Metal chassis of the thermal itself! one in a million". By the way, take this opportunity to write this experience. Best regards From Luis Alfonso Galindo From Colombia.
