Stopped working while using..is there a reset button?

Riccar uses an external thermal reset which is more reliable than most brands which use a thermal reset built into the motor. On your Riccar it will be on the back on the bottom left. It is a little tiny button that you will hear "click" when you push on it if it has been popped. If not it will not push in and you won't hear the click. The older models did not all have a reset button. If you have to keep pushing the reset it means that most likely you have a clog somewhere or the bag is full. It's rare but occasionally a thermal reset button may go bad and need replaced.

Check the drive belt. could be broken. Not sure about reset button but i would say it has to do with the belt.

Most likely the belt needs to be replaced. Clean hair and string from brush every time you use it to prolong the life of the belt.be replacing the belt.

Vacuum cleaners do not have reset buttons instead it would have a thermal protection breaker integrated within the motor if the motor overloads it will shut off but will start again as it cools down.Check to make sure the outlet has power in it first. Vacuum cleaners are usually reliable since they are not subjected to prolonged use unless it is used in commercial environment, but a common problem with it is a bad internal connection usually around the motor area due to vibration.

Make sure the brush is cleared and clean, press the reset button, and try again.
If the motor runs, but the brush doesn't turn, it's likely due to a broken belt. Have it replaced by someone who knows what they're doing.
I strongly recommend taking it into an authorized shop.

try changing the belt

What do you want to reset? Do you mean the motor has stopped working? There is no "reset button". The motor has an automatic cut-out, which will operate if the motor gets too hot and will reset itself when it cools. If the motor will not work when it's cool, then you have an electrical problem which will probably need professional attention.

hi welcome to fixya you need to replace belt if belt is ok than you burnt out the motor please check belt first as it is cheaper thank you for useing fixya please rate

While there's no reset button it's not uncommon for the internal thermal switch to trip to an "open" position. This internal, no-access-switch opens when the motor gets hot, it protects the motor from overheating to the point of failure. Bissell's website states that if the thermal switch is tripped let the vacuumm sit for a half hour and then it try it again.

If it doesn't work you might then try Tech610's suggestions.
