This seems ridiculous to me. Other than the electricity wasted, I cannot see how the consumer was harmed in this situation. Sure, they have every right to be ticked off, but for Pete’s sake, ovens are made to be turned on and left on for hours. This was an electric range, so there’s not even a CO hazard.
I suppose the argument could be made that if an electric oven is left on it could, somehow, malfunction, spew sparks, and start a fire. Is the same not true of an electric heater? Wouldn’t it then be considered negligent to not set the thermostat so the heater could not come on? What about the plumbing system? If left pressurized, and if a leak developed, serious damage to the property could occur. Under the same logic, could the inspector be fined for not shutting off the water supply before leaving?
The respondent also had another strike against him for non-notification of name use. I wonder how much that played into it.
As for the oven issue, I think it’s possible that TREC was throwing the complainant a bone.
