Could be different in other countries, but at the cost of the microwave ovens in the US, the cost of a new megatron tube and shipping is probably as much if not more than a replacement oven. A long time ago I decided that it is just not worth it to do most repairs (if you have to buy parts) on items costing under $ 500. If you have to get someone else to repair an item, just replace it. |
| Look165 <look165@numericable.fr>: Feb 13 04:17PM +0100 I totally agree. Sometimes, it is cost effective to change the oven instead of fixing it. Fixing it needs to get a new magnetron with the exact footprint if not it will not be OK. The only to check is the filament ; if it is OK, the problem is somewhere else (I think the HV capacitor or the diode). It can happen that the mains transformer is out, but rare.

| technowb <pietrarca@gmail.com>: Feb 13 08:36AM -0800 Thank you guys, in this case it should be worth to repair it since the oven is 5 years old and in pretty good conditions: the only issue is with microwaves features, but it still works as an oven with grill. It's a built-in big "luxury" model that still costs around 700€ new: it broke too early in my opinion because it was always been used following the rules (I am sure of that, It's my oven.. :) ) The official tech support said that I would need to buy a new one because they can't find the magnetron, but I cannot afford another expense of that kind - in particular for a product that can't be repaired after too little time.. I think that unless I find the same exact magnetron I will go for the suggested alternative, at least It's worth a try. Do you know what would happen if the alternative is a wrong option? Would I risk frying inverter module or something else? Given the price of the spare parts I could also think of selling those to buy a new one "with some discount". Thank you again |
