# Pitco SG18: Used-Buy Risk, Repairs & What to Check | KitchenRisk

> Used Pitco SG18 buying guide, hi-limit safety thermostat risk, repair costs and what to inspect.

**Verdict:** inspect

High-volume commercial gas fryer with a very deep OEM parts catalog (hi-limit safety thermostat ~$210, ignition module ~$228); Parts Town's own part description confirms the hi-limit switch is a safety device that shuts the unit off before the oil overheats, so during inspection verify the pilot lights, the burner ignites and modulates cleanly, and the manual-reset hi-limit has not been tripped repeatedly.

**Documented failure risks:**
- Hi-limit safety thermostat: OEM hi-limit switch (Pitco PP10084, manual-reset, 450F trip point) lists at $210.00 on Parts Town. Per Parts Town's own product description, "A Pitco PP10084 Gas Hi Limit Switch is a safety device that shuts the unit off and prevents the oil from overheating," and it fits SG14/SG18-family fryers. A tripped or failed hi-limit is a direct no-heat/lockout failure mode and, because it is a safety device, repeated trips should not be ignored during inspection.
- Ignition module: OEM ignition spark controller (Pitco 60152001-CL, 24VAC) lists at $228.00 on Parts Town, fitting the "SG & SGF-14/18/24 Solstice Fryer" family. Pitco's own IOM confirms these fryers use a matchless ignition system that must "automatically light the pilot, and heat up to set temperature" on power-up; a failed module presents as a fryer that will not light or re-light after a delight cycle.
