Troubleshooting - Quincy lab Analog Series Operating Manual

Chamber Loading
The oven's chamber temperature stability can be affected by changes in ambient (room) temperature and/or equipment
running in close proximity (creating microclimates) or cycling on the same electrical circuit. Take time to see how unit
location or changes in room temperature from seasonal heating or air conditioning may influence the oven's set
temperature. For best chamber temperature stability, keep the ambient temperature stable.
Thermal Safety Reset (Snap Disc)
Oven Safety Reset-
of the user, if the unit exceeds its maximum temperature, an internal safety "snap disc"
will cut power OFF to the unit until it is manually reset (FIG. 7).
To Reset
- disconnect the oven from power. Next, lay the oven on its back and
remove the bottom cover. Locate the round "snap disc" and push on the button to reset.
Maintenance / Cleaning Procedures / Common Replacement Parts
The Lab Series Ovens are designed to be virtually maintenance free. But operational safety requires periodic cleaning
and chamber temperature accuracy verification (see calibration and temp. range adjustment insert for more information).
Cleaning Procedure -
exit ports clear of obstruction and clean of dust and dirt. To reduce the risk of fire, it may be necessary to remove the
bottom plate cover to clean or vacuum any dirt and dust build-up. To clean the exterior and interior surfaces, use a
damp cloth or an all-purpose cleaner. Avoid commercially available oven cleaners.

WHAT TO DO BEFORE CALLING TECH. SUPPORT
1. Check if the unit tripped a GFCI outlet or fuse. Try a non GFCI
power outlet connection before moving to number 2 on this list.

Reset' section above for more information.
3. Check all wire connections in the electrical area (bottom) and
make sure there are no loose or disconnected wires in the unit.
1. Check thermal fuse in the back of the thermostat is not blown
or broken. Repacle if blown/broken.
2. If the oven does not heat, overheats, or does not maitain a
setpoint temperature, it's an indication of a bad/broken/old
thermostat. Replace thermostat on the unit.
