Belling 335 oven not heating up?

Belling 335 oven, original fault was oven not heating up, LHR hotplate & control light not working. Changed thermal fuse and rectified LHR hotplate & light problem, however, the oven still does not heat up even though both elements are ok. This only leaves either the thermostat oven control or a YELLOW spade terminal lead that is connected to one terminal of both elements but disconnected at other end. Can a cold test be done on the thermostat by multimeter to prove if it is ok before buying new one? Hope this is explained well enough for someone to offer a solution. Thanks in anticipation.
