Whirlpool Dryer Error Code 87

Error code 87 on a Whirlpool dryer indicates an Upper Axial Probe Fault. This means the control board has detected an abnormal signal from the temperature probe located in the upper axial position within the drum cavity. The dryer may stop operating or behave erratically until the fault is resolved. The root cause is typically a failed probe, damaged wiring, or a loose connector.

Continuing to operate the dryer with error code 87 active is not recommended. The upper axial probe is part of the thermal monitoring system, and a faulty reading means the dryer cannot accurately track internal temperatures. This could result in overheating, incomplete drying cycles, or unsafe operating conditions. The dryer should be inspected and the fault resolved before resuming regular use.

Resetting the dryer by unplugging it for a few minutes may temporarily clear the error code display, but it will not fix the underlying hardware fault. If the upper axial probe, its wiring, or the control board has an actual defect, the code will return once the dryer resumes operation. A proper repair requires identifying and correcting the failed component rather than relying on a reset.

Some causes of error code 87 can be addressed without professional help, such as reseating a loose connector or inspecting the wiring harness for obvious damage. However, replacing the upper axial probe or the main control board requires comfort with appliance disassembly and basic electrical testing using a multimeter. If you are not comfortable working with internal dryer components, a qualified technician should perform the repair.

Repair costs depend on which component has failed. If only a connector needs reseating, the repair may cost nothing beyond your time. Replacing the upper axial probe typically falls in the range of $20 to $80 for the part, while a new main control board can range from $100 to $300 or more. Adding professional labor costs generally brings the total repair to somewhere between $100 and $400 depending on the specific fault and your location.
