Samsung Microwave Error Code E-32

E-32 on a Samsung microwave indicates a weight sensor short circuit error. The microwave has detected that the electrical circuit connected to its weight sensor is experiencing a short, meaning current is flowing through an unintended path. The appliance halts operation when this fault is detected to prevent further electrical damage. Resolving it requires inspecting the sensor, its wiring, and potentially the control board.

No, you should not attempt to use the microwave while E-32 is active. The error indicates a short circuit condition in the weight sensor circuit, and operating the appliance with an unresolved electrical fault could cause further damage to the control board or create a safety hazard. Keep the microwave unplugged until the fault is properly diagnosed and repaired.

Repair costs vary depending on the root cause. If only connector cleaning or a wiring harness repair is needed, costs could fall in the range of $50 to $150 for a service call. Replacing the weight sensor itself typically adds $30 to $80 in parts. If the control board is the source of the fault, the repair cost can rise to the $150 to $350 range, at which point comparing the repair cost to the price of a replacement microwave is worthwhile.

Some causes of E-32 are accessible to a skilled DIYer, such as cleaning corroded connector terminals or inspecting the wiring harness for visible damage. However, working inside a microwave carries serious safety risks because the high-voltage capacitor can retain a lethal charge even after the unit is unplugged. If you are not experienced with discharging capacitors and handling microwave internal components, this repair should be handled by a qualified technician.

A power reset, such as unplugging the microwave for a few minutes and plugging it back in, may temporarily clear the display, but it will not resolve the underlying short circuit. If the sensor or wiring fault still exists, the E-32 code will return as soon as the control board re-evaluates the sensor circuit. A lasting fix requires physical inspection and repair of the faulty component.
