GE Dryer Error Code 16

Error code 16 on a GE dryer signals a UI-MC Heartbeat Timeout, meaning the User Interface board and the Main Control board lost communication with each other for 60 consecutive seconds. The dryer shuts down and displays this code to prevent unsafe operation. The fault can originate from the wiring harness connecting the two boards or from a failure in either board itself.

Unplugging the dryer for a few minutes may temporarily clear the error code, but it will return if the underlying communication problem has not been resolved. The 60-second timeout is a persistent fault condition tied to an actual hardware issue, not a software glitch. A reset is useful for confirming whether the fault is intermittent, but it is not a permanent fix.

Repair costs vary depending on which component has failed. If only the wiring harness needs replacement, costs are generally lower, often in the range of $50 to $150 including parts and labor. Replacing a UI board or MC board typically runs higher, with total repair costs often falling between $150 and $400 depending on the specific board, part availability, and local labor rates. Getting a diagnostic estimate before authorizing repairs is advisable.

Some DIYers with appliance repair experience can address this error by inspecting and reseating the wiring harness connectors between the UI and MC boards, which requires accessing the dryer's control area. If the harness connections are secure and undamaged, the repair typically advances to replacing one or both control boards, which involves working with electronic components and wiring. If you are not comfortable working inside appliances, a qualified technician is the safer choice.

The dryer will typically not operate normally while this error is active, as the control system halts operation when the communication link between boards is lost. Attempting to force the dryer to run with a known board communication fault is not recommended. Address the underlying cause before resuming regular use.
