DUTCHMEN ASPEN TRAIL 2060BH – LP Gas Detector Replacement

Complete repair guide for the DUTCHMEN ASPEN TRAIL 2060BH – LP Gas Detector Replacement.

Parts & Tools You’ll Need

Step 1: Diagnose the Faulty Detector Unit

Start by locating your existing LP gas detector, typically mounted on an interior wall near the kitchen or sleeping area of your Aspen Trail 2060BH. Press the test button on the detector—if it doesn’t beep or produces a weak sound, the unit has likely failed and needs replacement. Check the manufacturing date on the back of the unit; LP detectors have a 10-year lifespan and should be replaced regardless of function if they’re approaching or past this age. Document the model number and wiring configuration before proceeding, as this will guide your replacement choice between the Safe-T-Alert 35-742-WT, MTI Industries 35-742, or Kidde dual-sensor options.

Step 2: Disconnect Power and Remove Old Unit

Turn off the 12V DC power to your detector by switching off the circuit breaker or battery disconnect switch on your trailer’s electrical panel. Carefully unscrew the detector from its wall-mounted bracket, typically using a Phillips head screwdriver on two to three mounting screws. Gently pull the unit away from the wall and disconnect the 12V DC wiring harness by either untwisting wire nuts or unclipping the quick-disconnect pigtail connector, depending on your model. Take a photograph of the wire configuration (typically red for positive, black for negative, and sometimes a green or white ground wire) before full disconnection to ensure correct reinstallation.

Step 3: Prepare Wiring for New Detector Installation

Inspect the existing 12V DC connector pigtail wiring lead for damage, corrosion, or burnt insulation; replace the entire lead if any damage is visible using the provided 12V DC Connector Pigtail Wiring Lead. Strip approximately 1/4 inch of insulation from each wire end using a wire stripper to expose fresh copper. If the old detector used wire nuts, remove them and discard; prepare to use either the existing quick-disconnect connector (if compatible with your new unit) or the Wire Nut Cap + Tape Insulation Kit included with your replacement detector. Ensure all exposed copper is clean and free of oxidation, as poor connections can cause detector malfunction or intermittent false alarms.

Step 4: Install the New LP Gas Detector Unit

Carefully connect the new detector’s wiring harness to the prepared 12V DC pigtail leads, matching positive (red) to positive and negative (black) to negative; secure connections with either wire nuts from your kit or the unit’s quick-disconnect if available. Wrap each wire connection with electrical tape from the Wire Nut Cap + Tape Insulation Kit, overlapping the tape by 50% as you spiral down the wire to create a weatherproof seal. Position the new detector onto its wall-mounted bracket—for the Safe-T-Alert 35-742-WT or MTI Industries 35-742 models, align the bracket slots and insert the unit at a 45-degree angle, then twist clockwise until fully seated. Secure the unit with the provided screws, tightening to a snug fit (approximately 8-12 inch-pounds) without over-tightening, which can crack the plastic housing.

Step 5: Inspect LP System Connections and Regulators

Before restoring power, visually inspect all visible LP supply lines running from your propane tank to the two-stage regulator and on to the stove and water heater connections. Check for any cracks, kinks, or corrosion in the copper or flexible tubing, and verify that all threaded connections at the regulator inlet are hand-tight; use an adjustable wrench to snug them an additional quarter-turn if needed (do not exceed 15 foot-pounds of torque on regulator fittings). Locate the regulator’s pressure relief valve and confirm it’s not weeping or hissing, which would indicate a failed seal requiring LP Two-Stage Regulator Replacement. Document the condition of all connections photographically so you have a baseline for comparison after testing.

Step 6: Execute Propane Leak Detection Testing

Turn on your trailer’s battery or shore power to restore 12V DC power to the newly installed detector, then press the test button to verify it beeps loudly (should sound for 3-5 seconds); if it doesn’t respond, power down and recheck all wiring connections. Mix the Propane Leak Detector Spray Bottle according to package instructions (typically a soap-based solution) and spray the solution directly onto every LP connection point—the regulator inlet, all copper line fittings, and appliance connection points at the stove and water heater. Watch carefully for bubble formation while the detector is armed and monitoring; bubbles indicate an active LP leak that requires immediate tightening or component replacement. Allow the solution to dry completely between test points, and repeat the spray test on any suspect connection twice to confirm results before declaring the system safe.

Step 7: Final System Testing and Verification

With the propane system pressurized and the new LP detector actively monitoring, light your stove burners and water heater pilot to verify the detector does not trigger a false alarm under normal operation. Allow the system to run for at least 10 minutes while you move the detector’s test cord (if equipped) near the stove to verify its sensor is functioning correctly—the detector should remain silent during normal operation. Record the installation date and new detector model number in your maintenance log, setting a calendar reminder for the replacement date 10 years from today. Inform all trailer users that the detector is now installed and functional, and instruct them to immediately exit the trailer and move upwind if the alarm sounds, never assuming it’s a false trigger.
