Checking Temperature In The Convection (Oven) Mode; Error List - Sharp AX-GX2T(R) Service Manual

[5] CHECKING TEMPERATURE IN THE CONVECTION (Oven) MODE

The following test procedure should be carried out with the oven is a fully assembled condition (outer case fitted).
It is difficult to measure the exact temperature in the convection oven. An accurate thermocouple type temperature tester must be used. A low priced
bi-metal type thermometer is not reliable or accurate. Position the thermocouple in the center of the oven cavity. The temperature should be checked
with outer case cabinet installed and set the oven temperature to 250°C in the convection mode (Oven). Approx. 15 minutes after the oven is started,
the temperature experienced may be approx. 15°C more or less than set temperature, however, in most cases the food cooking results will be satis-
factory. Difference in power supply voltage will also affect the oven temperature. The Household power supply voltage may sometimes become lower
than the rated voltage and cause under-cooking. If the power supply voltage is 10% lower than the rated voltage, longer cooking time is required by
10% to 20%.
