GE Spectra Range Electronics display unit bad...
After a power surge, my oven electronics display doesn't light up and the
oven no longer works. The electronics package number is: WB27T10230 and the GE model No. is 191D2818P002. It looks like the PC board mounted power transformer (ETP41KAN41CA)primary is open (desoldered & tested with ohmmeter. The module is relatively expensive to replace. Would be nice to have a schematic showing the primary & secondary voltages. Anyone have any ideas about where to get an inexpensive module? I guess I could use an auto-transformer and apply an AC voltage to the secondary side; when the display lights up I could measure the value and then try to find a suitable stock transformer... Thanks in advance for any suggestions!! Don in sunny Florida |

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. The module is relatively expensive to replace. Google says $85 plus or minus. Would be nice to have a schematic showing the primary & secondary voltages. 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. Anyone have any ideas about where to get an inexpensive module? 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 guess I could use an auto-transformer and apply an AC voltage to the secondary side; when the display lights up I could measure the value and then try to find a suitable stock transformer... 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. Matt Roberds |
