My dad has a GE furnace (yes it's old) that the gas valve went out on. We went to supply house and bought a Honeywell vr8300a replacement.
On the old valve it had the TH/TR and M - M terminal points. The M - M was for a fusible link with two red wires coming from it. However in the new valve it TH/TR and then only Convenience terminals, not the M - M.
