🔧 **WATCHDOG TECHNICAL ALERT — SAMSUNG RANGE INFINITE SWITCH**
**Model:** NE58F9710WS/AA — Version 02
**Application:** Right Front Triple-Zone Surface Element
**Original switch:** PER001-03 T (gray body)
**Cataloged replacement:** DG44-01007B (blue body)
**Replacement identified through further research:** DG44-01008A
⚠️ **POTENTIAL PART SUBSTITUTION / TERMINAL CONFIGURATION ISSUE**
During a recent repair, we replaced a damaged triple-zone surface element. Several days later, the customer reported improper regulation of the innermost heating zone.
We ordered DG44-01007B, the replacement listed in the parts database.
Upon installation, the replacement caused an immediate electrical short, visible arcing, and a circuit breaker trip when power was restored.
We removed the replacement and reinstalled the original PER001-03 T switch. The range powered up normally, and the remaining burner functions operated.
**IMPORTANT FOR FELLOW TECHNICIANS:**
The original gray switch and blue replacement have different terminal arrangements. Do not assume that wires can be transferred by physical position.
Our subsequent research points to DG44-01008A for this application. We are requesting confirmation of the correct OEM replacement and correction of any inaccurate parts listings.
The exact cause of the short has not been independently established, so this is a field warning rather than a confirmed defect finding.
**Please verify the original switch markings, terminal designations, wiring diagram, and replacement compatibility before energizing the circuit.**
Sharing this to help other technicians avoid unnecessary callbacks, damaged components, and repeated parts-ordering problems.
