Hello
The High Limit ("snap disc") switch for the Whitfield and similar pellet stoves is rated at 250 Degrees F.

In stoves like the Whitfield, there are 2 High limit Switches.

BLOWER HIGH LIMIT DISC - Monitors temperatures on the firebox convection jacket and is designed to detect an over fire condition. It controls power available to the Feed System. If tripped “Open” power is lost to the Feed System. Inspection of the convection air paths, the blower voltage output readings, the integrity of the blower motor and all wiring is recommended. All ash collection points within the stove should be checked to remove any obstructions.
INLET HIGH LIMIT DISC -Monitors temperatures below the grate and in the inlet air path and is designed to detect reverse flow (caused from negative pressure – tight houses which may not supply adequate combustion and ventilation air.) It controls power available to the Feed System. If tripped “Open” power is lost to the Feed System. Inspection of ash collection points within the stove should be checked to remove any obstructions.
Check your Stove's Service and Maintenance Guide for your switche(s) location(s) and high limit spec to see where they measure the temperatures and what pwr is disconnected when they open up.
