Riccar 8955 sweeper won't run...where is thermal protection switc

The reset button does not have a significant amount of movement in response to pressing to with a paper clip or ball point pen. If the vacuum does not start upon pressing the button, then either the thermal protection circuit is not why the vacuum stopped in the first place or the reason the thermal protection circuit tripped has not been cleared. Quoting from the manual


"Your Riccar vacuum cleaner comes equipped with a Manual Reset Thermal Fuse Protector. This thermal protector is designed to protect your vacuum cleaner from overheating due to a restriction in airflow (i.e. clogged hose, operating the vacuum without a bag). Should this situation occur, the thermal fuse protector will safely shut off the vacuum cleaner to avoid any potential damage. NOTE: To determine it was the thermal fuse protector that turned off your vacuum
cleaner, please refer to the vacuum cleaner's headlight. If the headlight is on while the motor is off, then the thermal fuse protector did safely shut down the motor. If both the headlight and motor are off, then there is some reason other than the thermal protector (i.e. pulled plug) your vacuum is off.
To reset the thermal fuse:
. Unplug the vacuum cleaner

1. Check for problem - over-filled bag, clog in hose, clogged filters, etc.
2. Correct problem
3. Locate "tripped" fuse - the small white button located on the bottom of the back side of the main body (roughly one inch to the right of the left wheel)
4. Using a pencil, paper clip or other pointed object, push the reset button in
5. Plug vacuum cleaner in and resume use"

Remove the screws holding the bottom plate on. Remove bottom plate. If it's an 8955 or model with clutch to shut off the brush roll remove the rod that goes from the lever to the clutch. Look closely how the rod and brush roll are positioned in the vacuum so you can reinstall it the same way. Remove the brush roll and install the new belt and then put back together as it was.

Start by checking the reset button on the back. It will shut the vacuum off if their is a clog or restriction somewhere.
