GE Spectra Range Electronics display unit bad...

Power surges sometimes only blow a transformer primary. If so, some transformers can be fixed. If there are three legs on the primary, you MAY be able to use the other leg, as long as it's not a 120/220 volt transformer. Sky

That sounds like the drawing number of the electronics. The model number of the whole range will most likely start with a J.

Google says $85 plus or minus.

Doesn't exist.

Quite often these will have a simple power supply - the transformer secondary will go to a bridge rectifier and a filter cap. Look at the voltage rating printed on the filter cap and divide by 1.4 to get a maximum RMS AC value for the transformer. It could be anything but I'd guess it might be a "standard" value like 6, 12, or 24 V.

Call around. A local independent parts distributor may be able to give you a good price. (In Florida, try Marcone.) I've looked up lots of appliance parts on the Web and then gone down to my local guy and bought them cheaper.

I wouldn't use the auto-transformer output directly. I'd find something like a 24 V, 2 A transformer, and wire the secondary to the range control and the primary to the autotransformer. I'd also try and wire an ammeter in series with the 24 V output so I could shut down if the current goes way up.

Disclaimer: I used to sell appliance parts for GE, but I don't anymore.
