Yes, a furnace requires a ground wire as part of its electrical system. The ground wire provides a safe path for electrical current to flow to the ground in the event of a fault, such as a short circuit. The ground wire is typically a green or bare copper wire that is connected to the metal frame of the furnace and to the grounding system of the building.

Different furnace manufacturers may have slightly different ground wiring requirements, so it's important to consult the manufacturer's instructions when installing or modifying a furnace. However, regardless of the manufacturer, it's important to have the ground wiring installed correctly by a licensed electrician to ensure it's done safely and up to code.

You need a 3 conductor wire with ground. For example if you had a 30 amp breaker for that outlet you would need 10awg 3w/ground. That's 10 gauge 3 conductor with ground and replace the old wire back to the panel.

New furnace and thermostat now air conditioner compressor doesn't work?

If you replaced the furnace and thermostat this past winter, and now the A/C doesn't work. You probably just have a loose control wire. Check the yellow wire at the stat. It should be on the Y terminal. Next, look inside the furnace at the terminal block. The condenser wire should have two conductors. One hooks up with the yellow wire on the Y terminal of the terminal block. The other hooks to the C terminal. Always turn off the breaker to the furnace before working on any wiring. No need to fry the transformer.
