Question 1

My RV water pump won't turn on, what should I check?

Accepted Answer

First, confirm the water pump rocker switch on your control panel is set to ON, it is usually labeled 'Pump' near the kitchen, bathroom, or main panel. Then check that the fresh water tank has water in it, and that the service bay valves are set to NORMAL, not TANK FILL or CITY. Open a faucet for 30 seconds to let air purge. If the pump runs but no water flows, you likely have an empty tank or a closed valve at the service bay. Camphost can walk you through this step by step for free at mycamphost.com.

Question 2

Why won't my RV slide-out move?

Accepted Answer

The top causes are operator error, not mechanical failure. Check these in order: key fully OUT of the ignition, parking brake firmly ON, engine running or RV plugged into shore power (slides pull heavy amps), leveling jacks deployed on stable ground, and the battery disconnect switch ON. Most class A and C motorhomes will refuse to move a slide if any of those conditions are missing. If none of that works, check the slide fuse in the 12V panel before calling for service.

Question 3

Why is my RV refrigerator not cooling?

Accepted Answer

RV absorption fridges only work when the rig is level within about 3 degrees, so that is always the first check. Second, switch modes between propane and electric, a stuck mode is a common cause. Third, absorption fridges take 4 to 8 hours to cool down from warm, so they are not like a home fridge. Fourth, make sure the fridge is not packed too tight, airflow matters.

Question 4

Why won't my RV generator start?

Accepted Answer

For Cummins ONAN and most onboard generators, check these in order. First, fuel level, most ONANs stop drawing fuel at 1/4 tank to prevent stranding you. Second, house battery voltage, need at least 12.4V. Third, the generator's own breaker, which is on the generator unit itself. Fourth, prime the fuel system by holding the stop/prime button for 15 to 30 seconds (you will hear the fuel pump quiet down), then hold start for 5 to 10 seconds. If it starts and dies after a few seconds, that is almost always the low-oil shutdown, check oil on the generator.
