Appliances; Water Heater; Air Conditioner - Coachmen RV Mirada General Maintenance & Troubleshooting

Unless you have experience in working with LP gas appliances, we recommend having your appliance main-
tenance requirements performed by your Coachmen dealer or an appliance manufacturer authorized
service center.

WATER HEATER

Refer to your water heater owner's guide for operation and maintenance instructions. Twice a year do the
following:
✔ Check electrode for cracked porcelain and make sure gap between electrode and ground is set at 1/8".
✔ Clean module board circuits with a pencil eraser.
✔ Inspect and clean flu baffle. Presence of heavy soot formation indicates improper burner operation.
Have a qualified technician clean flu baffle or follow instructions in water heater owner's manual.
✔ Maintain proper LP gas pressure at 11 inches Water Column, this needs to be done by a qualified
technician.
REFRIGERATOR
Refer to your refrigerator owner's guide for operation and maintenance instructions. Twice a year do the
following:
✔ Check for obstructions in upper & lower vent areas (i.e. spider webs, birds nests, etc.) Use a soft
bristled brush to dust off the debris. Keep area at the back of refrigerator clean and free of debris.
✔ Check LP connections to ensure they are tight and not leaking. With LP gas supply on, use a
non-corrosive bubble solution on LP fittings. If bubbles are noticed – IMMEDIATELY shut off gas
supply and have a qualified RV Service technician repair leak source.
✔ Maintain proper LP gas pressure at 11 inches Water Column, this needs to be done by a qualified
technician.
✔ Inspect and clean flu baffle. Presence of heavy soot formation indicates improper burner operation.
Have a qualified technician clean flu baffle or follow instructions in refrigerator owner's manual.
FURNACE
Due to the complex nature of the appliance a qualified RV technician should perform furnace mainte-
nance at least once a year; more, if use of furnace deems necessary.
There are four important areas for proper operation of the furnace. They are:
1. Return Air: Keep return air grill free from obstructions.
2. Ducting: The ducting system is designed to meet the furnace manufacturer's specifications. Closing
off ducts or covering them may cause unnecessary operation trouble.
DO NOT store items on ductwork in cabinet spaces.
3. Maintain proper LP gas pressure at 11 inches Water Column, this needs to be done by a qualified
technician.
4. Voltage Fully charged batteries are also vital to the proper operation of the furnace. Keep batteries in
good working order and fully charged at all times. Refer to battery maintenance on page 31.

AIR CONDITIONER

Refer to air conditioner manufacturer's owner's manual for operation and maintenance instructions.
✔ Periodically remove return air filter. Wash with warm water and soap, let dry and reinstall.
• DO NOT run A/C without filter in place, dirt may accumulate on evaporator coil and substantially
affect the performance of the unit.
• Filter may require more frequent cleaning if environment deem necessary (i.e. smoky, dusty, etc.).
✔ Periodically check exterior cover for damages; if damages are present, have your Coachmen dealer repair.
