Maytag Dryer Error Code OPEN S.A.F.E. SYSTEM PROBE FAULT

This fault means the temperature probe for the dryer's S.A.F.E. system has been detected as either open-circuit or shorted by the microprocessor. The S.A.F.E. system monitors temperature to prevent overheating, and without a valid probe signal the dryer will not operate. The fault points specifically to the circuit running from microprocessor J3 connector pin 7 through the red wire to J10 connector pin 1.

No, you should not continue using the dryer while this fault is active. The S.A.F.E. system probe is part of the dryer's overheating protection circuit, and operating without a functional temperature probe removes a safety safeguard. The dryer may also refuse to run at all while the fault is present, which is the intended protective behavior.

A power reset may temporarily clear the fault code display, but the fault will return immediately if the underlying problem has not been corrected. Because the microprocessor continuously monitors the probe circuit, any open or shorted condition will be detected again as soon as the dryer attempts to operate. The root cause, whether a wiring issue or a failed probe, must be diagnosed and repaired to permanently clear the fault.

A knowledgeable DIYer can address this fault by first inspecting the J3 and J10 connectors for loose or damaged pins and checking the red wire for visible damage. Using a multimeter to test continuity along the wire and resistance across the probe itself will help isolate the failure. If the probe has failed, replacing it is a relatively straightforward repair, though accessing internal components requires disassembling the dryer cabinet.

If the issue is a loose connector or a simple wiring repair, the cost may be minimal, primarily your time or a small charge for a service call. Replacing the S.A.F.E. system temperature probe typically costs between $20 and $80 for the part, plus labor if a technician performs the repair. Control board replacement, if needed, is the most expensive scenario, with parts ranging from $100 to $300 or more depending on the model.
