Safety Disclaimer

Gas appliances

Smell gas? Leave right away, don't touch light switches or phones inside, and call your gas utility or 911 from outside. Never open a gas valve, burner, gas line, vent or flue connection, or bypass a safety switch. Repeated lockouts, scorching, soot, or a CO alarm mean shut it off and call a licensed gas technician.

Electricity

Unplug it or switch the breaker off before you remove any panel. Don't test or replace wiring, control boards, heating elements or motors under power. If you see scorching, smell burning, or the breaker trips again, leave it off and call a qualified appliance technician or electrician. Never open a microwave's outer cabinet. The high-voltage capacitor inside can hold a lethal charge even when unplugged. Unplug it and call a qualified technician for anything past the checks here.

Pools and hot tubs

Water and electricity together can kill. Turn the equipment off at the breaker before you open anything, never touch equipment while standing in water, and stay out of the pool or spa if you feel tingling or suspect an electrical problem. Leave wiring, boards and GFCI faults to a licensed electrician or service tech.

Refrigerant

Don't open the sealed refrigerant system, cut or braze lines, or add refrigerant. That needs an EPA-certified technician. Turn power off at the breaker or disconnect before opening any panel, and leave capacitors, compressors and control boards to a pro: they can hold a dangerous charge even with the power off.

Water and scalding

Water heaters and boilers store very hot water under pressure. Never cap or block a relief valve, and keep clear of its discharge pipe. Turn the heater off and let the water cool before draining or flushing it.
