Before you troubleshoot any commercial machine, make sure it is safe to touch. If you smell gas, leave the building and call the gas utility from outside. If you smell burning, see smoke or sparks, or find water near electrical parts, switch off the power at the breaker and keep people away. Only after the equipment is safe does it make sense to check the simple things, such as whether it is plugged in, the breaker is on, and the water or gas valves are open.
Many injuries and fires start when someone tries one more restart on a machine that was already warning them. Staff are under pressure to get equipment working, and a quick checklist helps them stop at the right moments.
Stop and act: danger signs
| Sign | Do this | Do not |
|---|---|---|
| Smell of gas | Leave the building, call the gas utility from outside, then call us once cleared | Do not switch lights or equipment, use a phone inside, or relight a pilot |
| Smoke, flames or scorching smell | Get everyone out, call 911 | Do not open a door onto a fire or fight it in a duct |
| Sparks, buzzing or hot cord or plug | Switch off at the breaker if safe, unplug if you can without touching wet surfaces | Do not touch the machine with wet hands |
| Water on or near electrical parts | Turn off power at the breaker and keep the area dry | Do not stand in water near a live machine |
| Breaker trips repeatedly | Leave it off and call | Do not keep resetting or use a larger breaker |
| Guard, door lock or interlock bypassed or broken | Take the machine out of service | Do not run it to finish a shift |
Simple checks once it is safe
- Is the machine plugged in, and is the plug and cord undamaged?
- Is the breaker or disconnect on? If it trips, stop; do not keep resetting.
- Are water supply valves open, and is the drain free of obvious blockage?
- Is the gas valve open, and has the building gas supply been interrupted lately? Only open gas valves if you have no gas smell.
- Is the door or lid fully closed and latched?
- Is there a message on the display? Write it down exactly.
- Are filters, screens and vents clean?
What to leave to a technician
Opening electrical panels, testing live circuits, working on gas valves or burners, handling refrigerant, removing guards, and any work on boilers or steam equipment should be done by a licensed technician. These tasks involve shock, burn, fire, explosion or exposure hazards. A quick look at the exterior is fine; opening the machine is not, unless you are trained and the power is locked off.
Gas equipment in more detail
Gas appliances produce carbon monoxide if combustion is poor. Warning signs include yellow or lazy flames, soot, a pilot that keeps going out, and headaches or dizziness among staff near the equipment. If anyone feels unwell near gas equipment, move them into fresh air and call emergency services. Good ventilation and a working hood are part of safe operation. Have burners, flues and hoods inspected regularly.
Electrical equipment in more detail
Commercial machines often use high-amperage circuits, 208 or 240 volts, or three-phase power. Do not use extension cords or adapters to power them. Do not replace a breaker with a larger one to stop it from tripping, because the wiring will be overloaded. Cords that feel hot, plugs that are discolored and outlets that buzz need attention before the next use. In wet areas, GFCI protection may be required by code; ask a licensed electrician.
What to tell us when you call
- The make, model and serial number from the data plate.
- What happened, when it started and what you saw, heard or smelled.
- Any display messages, written exactly as shown.
- What you already tried, and whether the breaker tripped.
- Whether the machine is still in service or has been turned off.
We use that information to decide what parts to bring, and whether the situation needs an urgent visit. Same-day appointments are often available, and we confirm a three-hour arrival window when you book.
Training your team
Post a short sheet near the equipment with the three emergency steps: gas smell means leave and call the utility, smoke means get out and call 911, electrical danger means breaker off and keep clear. Show new staff where the breaker panel, the gas shut-off and the water shut-off valves are. Practicing this once saves minutes when it counts.

FAQ
Can I reset a tripped breaker?
Once, if there is no smell, smoke or water. If it trips again, leave it off and call.
Should I relight a pilot that went out?
Only if the maker’s instructions say staff may do it and there is no gas smell. If it keeps going out, call us.
What if I am not sure whether it is gas I smell?
Treat it as gas. Leave the building and call the gas utility from outside.
Do I need to turn off the power before cleaning?
Yes. Switch off and unplug the machine before cleaning parts near moving or electrical parts.
