Check it now, not during the first cold snap
Most people don't think about their block heater outlet until they're standing outside in the dark trying to plug in before a cold morning. October is a better time. Go out, plug something in, make sure it actually has power. If it doesn't, you want to find that out now, not when it's -30.
Test the GFCI
Most outdoor outlets in Grande Prairie are on a GFCI, the outlet with the little test and reset buttons. Sometimes the GFCI is inside on the panel or a nearby indoor outlet feeding it instead. Press test, then reset. If it won't reset, or it trips the second you plug something in, that outlet needs a look. Don't just leave it unplugged and forget about it all winter.
Check the cord and the outlet itself
A few things worth a quick look:
- Cracks in the outlet cover, or a cover that doesn't close properly anymore
- A block heater cord that's cracked, frayed, or has tape holding it together
- Rust or corrosion inside the outlet box
- The cord sitting in standing water or snow instead of up off the ground
None of this takes long to check. If the outlet looks rough, it's cheaper to deal with it in October than to have it fail in January.
Rental owners
If you manage a rental, block heater outlets are one of those things tenants assume work until the day they don't. A quick check before the first cold spell saves you a call at 6am about a car that won't start. Worth adding to a fall walkthrough.
Don't run extension cords all winter
If the block heater outlet isn't reachable from where the car parks, the fix isn't a 100 foot extension cord taped down across the driveway. That's a trip hazard, and the cord wears out fast sitting outside in the cold and wet. If you're doing that every winter, it's worth adding a proper outlet closer to where you park.
When to call an electrician
If the GFCI won't reset, if the outlet feels loose, or if you see any scorch marks or melted plastic, stop using it and call an electrician. Same goes if you want a new outlet added somewhere more convenient. That's not a DIY job in Alberta beyond basic permitted work in your own home, and an outlet that fails outside in the cold is more than just an inconvenience.
