Hi


Thanks for using FixYa. While the line is on go to breaker box see what size breaker you are running, increase to a twenty amp. If a fridge or freezer is on same line, find a new outlet on another line. Although your 20 amp circuit should be able to handle the two loads - if the fridge compressor should happen to cycle at the same time you’re cranking away at the treadmill...the two motors combined in-rush currents together may be close to overload.

Generally (and in compliance with Code article 210.52)...the refrigerator should already have its own dedicated circuit. But - in older homes... (Wired back before the 2 small appliance circuits plus fridge circuit in kitchen requirements codes were in place) you often will find other receptacles on the same circuit as the fridge. So having a dedicated circuit for the fridge isn't because it's a big power draw...only because it's an essential item....and a circuit you want to maintain power to avoid spoilage. The Treadmill should have its own dedicated 20 amp circuit...as recommended in the specs for the unit. That's not to say you'll burn the house down if you continue to operate the circuit as it....just that you are pushing it to the max IF both motors happen to peak at the same time.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks
