5550305006 Genuine Transformer 230V 50Hz for Electrolux Group Microwave Ovens, Replacement Microwave Transformer

Rated for a 230V, 50Hz supply, 5550305006 is a genuine Electrolux group microwave transformer. It converts household power into the much higher voltage the magnetron needs to heat food. Electrolux hasn't supplied a list of microwave models for this number, so confirm it against the label on the transformer inside your oven, or send the model and PNC from the rating plate through the parts enquiry form.

Transformer faults in a microwave oven

A microwave's transformer works hard every time the oven heats, and the windings can overheat, short or break down over the years. Common signs are an oven that powers up and counts down but leaves food cold, a heavy humming or groaning sound during heating, a smell of hot varnish, or a fuse that blows the moment heating starts. Because a shorted diode or failed capacitor can stress the transformer, a technician will usually test the whole high voltage circuit before replacing it.

Who should fit this transformer

Leave this one to a qualified technician. Even with the microwave unplugged, the capacitor can stay charged at a lethal voltage until it's discharged properly. The technician should check the diode, capacitor and magnetron, fit the new transformer with the original fixings and earth connections, and test the oven for microwave leakage before it goes back into use.

Questions about this part

Is a 230V transformer right for Australian power?

Australian homes are supplied at a nominal 230V, 50Hz, which matches the rating listed for 5550305006. That said, the transformer still has to match your microwave model, so check the number on the old part before you buy.
