RV Water Heater Repair & Diagnostics
No hot water, intermittent heating, ignition problems, electric-mode failures, leaks or tankless water-heater issues? MilTech RV provides mobile diagnosis and repair for common RV water-heater systems and related controls.
Don't Replace Parts Until the System Has Been Tested
An RV water heater that stops producing hot water can have several possible causes. The problem may involve 12-volt controls, 120-volt electric heating components, propane ignition, thermostats, wiring, switches, control boards, water flow or another component. Proper testing helps separate the actual failure from the symptom.
No Hot Water
Diagnosis when the water heater appears to operate incorrectly or does not produce expected hot water.
Propane Ignition Problems
Evaluation of accessible ignition, control and related components when the burner will not light or stay operating.
Electric Heating Problems
Troubleshooting of applicable 120-volt heating components and controls when electric mode is not heating correctly.

Diagnose. Explain. Repair. Educate.
A water heater that will not ignite does not automatically need a control board, and a unit that will not heat electrically does not automatically need a heating element. Power supply, switches, wiring, controls and other conditions can produce similar symptoms.
