Truma AquaGo Control Unit Assembly 77000-00113 for RV Water Heater — Open-Box, 25% Off

If your AquaGo won't ignite, throws an error code, or cycles the burner erratically, a worn internal control unit is a common cause; this OEM assembly replaces the board that reads sensors and fires the burner so hot water flows normally again.

Built specifically as the control unit assembly for the Truma AquaGo tankless water heater, designed to pair with the AquaGo control panel; confirm your current unit's part number before ordering, since Truma parts are model-specific.

Ships as the complete OEM control unit assembly, the genuine internal component Truma engineers for AquaGo service replacements; install by following the AquaGo owner's manual procedure, ideally by an RV technician familiar with propane appliances.

Manufactured to the same electrical tolerances and safety-interlock logic as the original factory unit, so ignition sequencing, temperature sensing, and shutdown protections operate exactly as Truma designed them, not an aftermarket approximation.

Made for motorhome, travel trailer, and fifth-wheel owners running a Truma AquaGo system who want factory-correct hot water performance restored at home instead of waiting on a dealer service appointment or replacing the whole water heater.

"You turn the tap expecting instant hot water, and instead the Truma AquaGo panel flashes an error code, the burner refuses to light, or the heater cycles on and off mid-shower. Before assuming the whole water heater is dying, check the electronics behind the display: the control unit assembly is the internal component that reads temperature and flow sensors, fires the ignition sequence, and enforces the safety shutdowns that make the AquaGo work. When it fails, symptoms show up as no ignition, inconsistent temperature, or a control panel that won't respond correctly, even though the panel itself looks fine. This is a genuine Truma OEM replacement, built to pair directly with the existing Truma AquaGo control panel already installed in your rig. It is not a universal or aftermarket substitute; it matches the same specifications as the control unit your AquaGo shipped with, so ignition timing, sensor input, and shutdown protections behave exactly as Truma designed. Because Truma parts are model-specific, confirm your current control unit's part number before ordering. Installation follows the same service steps outlined in Truma's AquaGo documentation: disconnect power, remove the failed control unit, install this assembly, then reconnect the existing control panel. Most owners have a qualified RV technician handle the swap, since the AquaGo runs on propane with gas safety interlocks, but a DIYer comfortable around propane appliances and 12V wiring can typically finish it without extra parts. This control unit assembly suits motorhome, travel trailer, and fifth-wheel owners who rely on a Truma AquaGo tankless water heater for on-demand hot water and want factory-correct performance restored without replacing the entire unit or waiting on a dealer service slot. Whether you're troubleshooting an error code, an AquaGo that won't ignite, or a heater that won't hold steady temperature, this replacement returns the core electronics to original operating condition."
