Frigidaire Washer Error Code E52

E52 means the control board is not receiving a tachometer signal from the drive motor. The tachometer monitors motor speed and sends that information back to the control board so it can regulate the wash and spin cycles. When that signal is missing, the washer stops and displays E52 to prevent damage. The issue can be in the motor itself, the wiring harness, or in rare cases the control board.

No, you should not continue running the washer while E52 is active. The control board cannot regulate motor speed without the tachometer signal, which means the motor could overheat or the drum could operate erratically. Stop using the machine and diagnose the fault before running another cycle.

Repair costs vary depending on what component has failed. If the fix is simply reseating a loose connector, there may be little to no parts cost involved. A replacement drive motor typically runs anywhere from $80 to $200 or more for the part alone, and professional labor can add another $100 to $200 depending on your area. A control board replacement, if needed, falls in a similar or higher range, so getting a diagnostic from a technician before ordering parts is worthwhile.

Some of the preliminary checks are within reach for a confident DIYer, such as inspecting and reseating the motor connector and looking over the wiring harness for visible damage. However, testing resistance between pins 4 and 5 on the motor requires a multimeter and some familiarity with reading electrical values. If the motor tachometer winding has failed, replacing the drive motor is a more involved repair that many homeowners prefer to leave to a technician.

A reset may temporarily clear the code from the display, but it will not fix the underlying problem. If the tachometer signal is still missing due to a failed motor winding, broken wire, or faulty connector, the error will return as soon as the machine tries to run again. The root cause needs to be identified and repaired for the code to stay clear.
