What to do if my Fisher Scientific Isotemp Premium 700 Oven has no power?
If your Fisher Scientific Oven isn't getting any power, first ensure that the unit is properly plugged in and turned on. If it is, the issue might be a defective circuit breaker, in which case you should replace it.
What to do if the Alarm LED stays on and control is higher than set temperature in Fisher Scientific Oven?
If the Alarm LED stays on and the control temperature is higher than the set temperature on your Fisher Scientific Oven, there are a few potential causes. First, the set temperature might have been changed to a value less than the actual temperature minus the alarm limit; in this case, wait for the actual temperature to cool to the set temperature. Alternatively, there may be a defective controller, which would require replacement. Finally, a defective control thermocouple could be the culprit; in this case, refer to the schematic and replace the relays.
Why is my Fisher Scientific Oven failing to heat?
If your Fisher Scientific Oven is failing to heat, several factors could be responsible. First, ensure that the set temperature is not lower than the actual temperature; refer to the Operation section for guidance. Other potential causes include a defective control thermocouple (replace it), poor heater connections (tighten connections at the terminal strip and/or heater), a defective heater element (check heater resistance on schematic at back of manual and replace if necessary), a defective controller (replace it), or a defective solid state relay (refer to schematic and replace the relay or safety relay). If the Temperature Device is disengaged or defective, replacement should be performed by factory authorized personnel only; disconnect power and contact Technical Services.
Why is the Fisher Scientific Oven temperature erratically high?
If your Fisher Scientific Oven temperature is erratically high, it could be due to a defective control thermocouple. If this is the case, you should replace the control thermocouple.
How to fix temperature off from independent thermometer in Fisher Scientific Oven?
If the temperature on your Fisher Scientific Oven is off compared to an independent thermometer, the calibration offset may need adjustment. You can begin by setting the offset to 0. See Display Offsets.
What to do if my Fisher Scientific Oven set display to “EEE”?
If the display on your Fisher Scientific Oven is showing “EEE”, it could be due to a few reasons. One possibility is that the set temperature has been changed to a value less than the actual temperature minus the high alarm limit; in this case, wait for the actual temperature to cool to the set temperature. Another potential cause is a defective control thermocouple, which would need to be replaced. Lastly, faulty or broken connections could be the issue; check the thermocouple connections at the rear of the temperature controller.
