Sthovd RV Water Heater Thermostat Limit Switch Kit 232306 & 232282 (AC & DC) — Overheat Protection for Suburban SW-Series

This replacement kit bundles two complementary thermostats and the necessary hardware to service many Suburban SW-series units. It combines an AC thermostat (232306) and a DC thermostat (232282) with adapter cables, switches and wire nuts so you can swap out faulty controllers that cause constant cycling, imprecise temperatures, or unsafe overheating. The components are built for the vibration, moisture, and heat common in mobile RV environments.

Which Suburban water heater models does this kit work with?

The kit was designed to be compatible with a broad range of Suburban SW-series water heaters. It lists direct replacements for part numbers 232306, 233534, 525007 and 232282 and supports numerous SW6, SW10, SW12 and SW16 variants. Always compare the original thermostat's shape, mounting, and terminal layout to confirm fit before installation.

• Compatible with SW6D, SW6DE, SW6DEL, SW6DEM and SW6PE/ SW6PER models
• Works with SW10DE, SW10DEL, SW10DEM, SW10PE, SW10PER
• Fits many SW12 and SW16 series units including DEM and DDE variants
• Replaces 232306, 232282, 233534 and 525007 thermostat part numbers

How do the two thermostats differ and what temperature ranges do they handle?

The kit contains a 120VAC thermostat (232306) and a 12VDC thermostat (232282) so you can service both AC- and DC-powered control circuits. Each thermostat performs temperature limiting and automatic cut-out to protect the water heater from overheating. The listed switching ranges give a clear idea of normal operating thresholds and the manual reset point for high-temperature trips.

• 232306 (120VAC) automatic range: approximately 113 °F to 140 °F
• 232282 (12VDC) automatic range: approximately 122 °F to 140 °F
• Manual high-temperature reset activates at about 185 °F
• Both provide overheat protection and can reduce dry-fire risk

What common problems does this thermostat kit fix and how reliable is it?

Replacing a failing thermostat with this kit resolves erratic heating, continual cycling, inability to hold set temperature, and repeated trips after resets. The components are manufactured from heat-resistant plastics and metals intended for long-term exposure to vibration and moisture inside RV compartments. Proper installation—ensuring thermal sensor plates contact the tank wall—helps ensure accurate readings and dependable operation.

• Stops continuous non-heating or abnormal heating behavior
• Prevents repeated trip/reset cycles caused by faulty controls
• Constructed with high-temperature resistant materials for durability
• Requires correct sensor mounting for accurate temperature sensing

How difficult is installation and what comes in the kit?

Installation is straightforward for anyone comfortable with basic RV electrical and plumbing safety: shut off power and water, remove the old assembly, attach the new thermostats with solid sensor contact to the tank, secure the bracket, and test for leaks and function. The kit supplies the parts you need to complete a standard swap, reducing the need to source miscellaneous connectors or switches.

• Includes 232282 (12VDC) and 232306 (120VAC) thermostats
• Comes with adapter cables, two manual power switches and wire nuts
• Installation needs tight sensor-to-tank contact and secure mounting
• Power-on test requires opening inlet, venting air, and checking for leaks

Who is this for: RV owners, fleet technicians, and mobile home service professionals who need a direct replacement for Suburban SW-series water heater thermostats. If your water heater shows temperature inconsistencies, repeated trips, or no heating on either AC or DC circuits, this kit provides the compatible parts and hardware to return the system to safe, reliable operation.
