The electric oven temperature controller circuit is composed of the power supply circuit and temperature detection control circuit, and it is shown in Figure 3-80. Power supply circuit is composed of the power switch S, fuse FU, power transformer T, rectifier diodes VDl, VD2 and filter capacitor C. The temperature detection control circuit is composed of electric hot thermometer Q, relay K, diode VD3, resistors Rl, R2, Crystal thyristor VT, neon light HL and electric heater EH. Rl and R2 use the 1/4W carbon film resistors or metal film resistors. C selects the aluminum electrolytic capacitor with voltage in 25V. VDl-VD3 use the 1N4007 silicon rectifier diodes.
