This is actually because the compressor can fail, generating heat and so possibly catching fire. Wires can also melt. I've seen far more than my share of appliances-turned-bonfires. Shorted wires, terminals, animal fur. Magnetrons and capacitors running amok. Those are especially fun when the microwave is mounted into wooden cabinets. Dryer belt pulleys freezing up causing friction rubber fires. The dangers abound, they just are never thought of until it happens. Now you have the extra fun of ICUs being on backorder 6+months (9/10 failures on all new models are ICU/touchscreen board failures). I'd really hate to be an appliance technician right now.
