GE Spectra Range Electronics display unit bad... Next Step
Hi, All..
Using the method suggested by Matt Roberds, I determined that I need a small power transformer (the bad one was mounted to the control unit pc board) that has the following specifications (or close to them): Primary: 115 vac Secondary: 8 vac, center tapped (4 vac + 4 vac). I've looked around at some surplus sites (All Electronics, Digikey, Allied, B.G. Micro, etc. but haven't been able to find one with those spec's. I can mount the xfmr on the stove chassis and run the leads to the pcb; just can't find an xfmr. Using the variac and a 24 vac xfmr, the unit came alive at about 3 vac and became active at 3.75 vac and very bright clock readout at 4 vac. Does anyone have any suggestions where I could find one in the range of 300 ma to 1000 ma? Thanks for any assistance!! Don in sunny Florida |

Thanks for any assistance!! Does the existing transformer have an open frame? Does the primary have continuity? If so you might want to consider rewinding the secondary. Or consider getting a 16V CT transformer with a 220 primary and running it on 110. http://www.mouser.com/catalog/624/1436.pdf |
