Common single-deck gas convection oven with active OEM parts support (temperature control ~$567, hi-temp door micro switch ~$82); Garland's own IOM confirms the door must be closed for the oven to heat -- opening it stops the heat and shuts off the motor and fan as a safety feature -- so during inspection verify the oven heats only with the door shut, that the door switch resumes heat immediately on closing, and that the thermostat holds the dialed temperature.

OEM temperature control (Garland 300867, IM2000, 150-500F) lists at $566.90 on Parts Town and appears directly in the MCO-GS-10 model's in-stock parts catalog. Per Garland's own IOM, "The oven will begin to heat to the temperature set on the thermostat dial" and "the temperature range is from 150F to 500F" -- matching this exact control's rated range -- so a failed or miscalibrated unit is a direct cause of an oven that runs cold, overshoots, or never reaches set temperature.
$567–$567OEM hi-temp door micro switch (Garland 4519715) lists at $81.59 on Parts Town. Garland's IOM states plainly: "The door must be closed for the oven to operate in cook mode. Opening the door will cause the heat to stop. The motor and fan will shut off. This is a safety feature." A failed door switch can present as an oven that never heats even when the door is closed, or one whose fan/heat does not stop when the door is opened.
