Short answer: no permit needed. If it plugs into an existing outlet (portable AC, plug-in range/dishwasher swap), no permit — but hardwired appliances or new plumbing/electrical connections are trade work needing permits. The full rule and its official source are below, with the code requirements and mistakes that trip up Orlando homeowners.

Key facts before you start

Order: settings before parts. Check Control Lock (hold ~3 sec to clear), Sabbath/demo mode, and delayed-start timer first — all make a working oven look dead (Whirlpool/GE official first steps). On self-clean models also confirm the door latch is fully in the unlocked position or bake won't run.
One-leg 240V trap: ranges need 240/208V on two hot legs; on 120V (one leg of the double breaker tripped) 'the clock may work but the burners will not heat properly' (GE). Cycle the double-pole breaker fully OFF, wait 1 min, then ON — even if it looks ON — before condemning any part; this also resets the electronic control.
Bake element: with the range unplugged AND breaker off, inspect the lower element for blisters, cracks, or breaks — visible damage = replace, a GE-documented DIY (two screws, pull element forward, pull spade connectors off terminals; secure the leads so they don't drop back through the rear insulation hole). If the oven floor is smooth, it's a HIDDEN bake element under the floor — not visually inspectable, treat as service/tech-level.
Temp sensor test (bakes wrong, F10/F30/F31 codes): unplug and measure the oven RTD sensor — spec is 1091 +/- 5.3 ohms at 75F (~1080-1100 at room temp, Frigidaire service data). Under 500 ohms or open/infinite = replace probe; if it matches the chart, the fault is the electronic oven control (EOC) board — hard stop, service.
Runs hot/cold but heats = not broken: +/-30F swing around setpoint is normal cycling (GE). Fix with the control's built-in calibration offset (up to +/-35F via Settings/keypad per owner's manual, retained through power failure) — don't replace parts for a temperature-preference complaint.
Gas oven, burners work: on new installs check the range's gas regulator shutoff — 'top burners will still work with the regulator valve off, but the oven will not' (GE). Turn on bake and look for the igniter's red glow; glow but no flame = weak igniter not drawing enough current (~3+ amps) to open the safety valve — replace igniter or call service; never DIY the gas safety valve.
