Can someone help me identify and cross reference part SG348, which looks like a dime size disc with 2 legs? It is likely thermistor or varistor. It was located by the bridge rectifier in control unit to the furnace blower control unit. It has manufacturer logo looking like "i" Thank you in advance.

Answer to my own question. SG-348 is NTC Thermistor made by RTI Electronics. This one is not listed but a reliable source said it is 1ohm surge- gard and can be replaced with SG-328.
