Answer Bhargav, it would be recommended that the interlock bracket that houses the door switches is inspected to ensure that the screws are not loose and that the door is making full contact. From there, the top door switch (MFG# WG02F01530), middle switch (MFG# WB24M198), and lower switch (MFG# WB24M199) would need to be tested for continuity to ensure proper operation. The top and bottom switches should show continuity only when the door is closed while the middle should show open. When the door is opened the switches would have opposite continuity readings. The main control (MFG# WB27M02980) relay for the transformer would also need to be tested for continuity to ensure it is not stuck in the closed position. Unfortunately, we do not carry these parts.
