Annual Preventive Maintenance and Inspection Requirements
In reading the various items in my owners manual, I see there are suggested Preventive Maintenance and Inspection requirements for many of the electrical and mechanical components in my trailer, a number of which must be done by a qualified service technician -- which I am most definitely not.
These include, among other items:
1. cleaning and inspecting the condensor and evaporator fins and evaporator blower wheels and blades on the air conditioner and heat pump,
2. checking and/or cleaning the air wheel, burner, combustion chamber and control compartment on the furnace,
3. removing and cleaning the burner asembly, and checking all ground and terminal connections on the refrigerator.
The questions I have are:
1. How important are these items to get done annually?
2. Who do you get to do them?
3. What is a reasonable cost that one could expect for them?
As an aside, there are many other items that I do, or at least think I could figure out how to do, including among others:
1. Cleaning and replacing filters on air conditioner and water filters.
2. Lubricating tongue power jack, and electric corner stabilizer jacks.
3. Checking ground fault circuit braker interruptor and LP gas sensor.
4. Checking water heater burner flue for spiders, mud daubers, etc. and preiodically draining and flushing.
5. Maintaining proper air pressure in tires, and checking lug nuts for proper torque.
