This could either be an issue with the computer gauge or heat sensor wire. There is a wire that connects directly from the heating element and into your temperature gauge. If this wire is damaged, loose, or disconnected, your temperature display will show either 000 or HH. To resolve the problem please follow the steps below:
- Start by disconnecting the large green connector behind your computer gauge and connecting it back in. Sometimes if this is slightly loose, you will get that error reading. If you’re facing the temperature gauge directly from behind, the two wires on the bottom right corner are your heat sensor wires. If you route them to the other side, they should go directly into your heating element.
- Make sure this wire is tightly connected.
- Try disconnecting them and reconnecting it just to be sure they’re tightly connected.
- If problem persists, you will need to replace the heat sensor wire.
