If the pop was from the meter(I assume it was since it doesn't work now), I would agree with Monel. If you had the meter set on ohms and measured a live circuit it will put a large current through the meter and possibly(in your case probably) blow the circuits in the meter.
Tip, always check the circuit for voltage before measuring the ohmage.
In the case of an oven, unplug the thing before you work on it!! Then check again that it is unpluged, then look one more time. Electricity kills.
kamiam, ovens do not have a bridge circuit. edit, second thoughts, there may be one in the ignitor circuit, havn't had to work on mine yet.
The meters I use(Flukes) are fused on the current inputs, but I don't believe they are fused on voltage or ohms. Experiance, I have blown the fuses and they still work on voltage and ohms.
