Range hood fan and light

Iíve got a 2014 Shamrock 183. The fan and light over the stove has stopped working. A black wire carrying power to the light switch with a jumper powering the fan switch has power. Both switches have power out. Power is present at the light bulb socket. The white ground wires from the light and fan go to a connector with green wire out to ground on the hood. One more white wire also connects to this ground connection. Anyone here run in to a problem like this? Iím thinking it has to be a bad ground somewhere for neither one to work.

How did you determine that there was power at the switches?

If you put the test leads between the positive and negative leads before the switches, is there ~12 volts present?

It has to have a positive and a negative to connect to, right?
That makes me believe that the negative is there, but maybe there's a connection issue somewhere. Either that, or you have two items that are both bad.

Highly unlikely BUT still possible.

Remove the bulb. Hook the alligator jumper from your test light to the range light's negative terminal. If the test light lights when you touch the point to the hot side, the ground is good and you're getting juice. That leaves the bulb as the culprit. Do the same with the vent fan.

On my range hood in my Coachmen the light was working but the fan not working. I took apart and there was an inline fuse soldered to a wire inside the unit that was bad. I replaced the fuse with an replaceable fuse and holder.

Clip the negative of the test light to the supply white wire and leave it there. If you have voltage at the switch then follow the switch wire about 18" to the fan. Any power there? There should be no connection of any kind between the switch and the fan motor. Or the switch and the light. If you have power then remove the tester from the white wire and connect it to the motor negative wire. If you lose power you have a break in the negative connection. The negative connection should have three wires there. Power negative, fan, and light. Possibly a 4th going to another device like the Furnace, fridge control circuits.

After getting in there and pulling and wiggling the wires, it started working and so far I canít make them quit again. I think the ground was somehow pinched under the board the microwave sits on and when it pulled free everything was good again.
