When the refrigerator will not run on 120-volt power
We check AC power, plug connections, the breaker and the selector switch. We use a multimeter or ohmmeter to test thermostat continuity and heater resistance. A refrigerator that will not operate on electric needs these checks, not a gas-pressure adjustment.
When the refrigerator will not run on LP gas
We check the gas supply and pressure first. We use a manometer at the refrigerator’s gas test point; for a Dometic refrigerator, the specified pressure there is 11 inches water column. That specification applies to that test point, not automatically to every absorption refrigerator. We then inspect the flue and burner for obstructions and check the ignition components.
Pump replacement and roof-sealant costs
RV water-pump replacement costs $150 to $275. RV roof-seam and penetration sealant treatment costs $600 to $1,500. The roof range is for sealant treatment at seams and penetrations, not a roof replacement. Neither range establishes a price for refrigerator diagnosis or repair.
Check the ground where your RV is parked
We check site conditions rather than assume the ground is firm and even. Harlingen-series soil is very clayey and smectitic, and it cracks when dry. Seasonal moisture changes can move soil and stress foundations. Although this soil is moderately well drained, water passes through it very slowly, and some areas are subject to rare flooding. In Harlingen, intense rain can also cause flooding where flat grades and slowly permeable soils limit drainage. Check the parking site for dry-ground cracks and drainage problems rather than judging it only by how it looks in dry weather.
