I'm still pretty new to RVing and trying to figure out the electrical side of things. We have a 2024 Tiffin Open Road and I'm not sure if I can use the dryer when we're plugged into a 30 amp hookup at campgrounds.
I've heard mixed things about whether dryers work on 30 amp service or if you need 50 amp. Some people say it depends on the dryer type? I'm honestly not even sure how to tell what voltage our dryer is or what that means for power requirements. Any guidance would be really appreciated!
Depends on dryer voltage. 120V dryers work on 30 amp with load management - turn off AC while drying. 240V dryers require 50 amp service. Check your specific dryer model specifications to confirm voltage requirements.
No, your Tiffin 2024 Open Road's dryer will not work when plugged into a 30-amp RV box. The washer/dryer combo unit in your coach requires 50-amp electrical service to operate properly. The dryer function specifically needs the 240-volt power that's only available through a 50-amp connection, while 30-amp pedestals only provide 120-volt service. You'll need to find a campground with 50-amp hookups or use alternative drying methods when connected to 30-amp power.
The fundamental issue is electrical power requirements versus what's available. Your 2024 Tiffin Open Road comes equipped with a Splendide or similar washer/dryer combo unit that requires 240-volt power for the dryer heating element. This 240-volt requirement can only be met through a 50-amp electrical connection, which provides two 120-volt legs that combine to create 240 volts.
When connected to a 30-amp pedestal, you're limited to a single 120-volt leg with a maximum of 3,600 watts of power. The dryer's heating element is designed to operate at 240 volts and cannot function on 120-volt power due to voltage requirements, not just power limitations. Even if it could operate on 120 volts, adding other coach electrical loads would immediately trip the 30-amp breaker.
Your coach's electrical management system may also prevent the dryer from attempting to start when it detects insufficient power availability. This is a safety feature designed to protect both your RV's electrical system and the campground's infrastructure from overload conditions.
Before attempting any troubleshooting, verify your power connection status by checking your electrical monitoring system or surge protector display inside the coach. Some newer Tiffin coaches have digital displays that show the incoming power configuration and available amperage.
Check your owner's manual for the specific electrical requirements of your washer/dryer unit. Tiffin typically includes detailed electrical specifications for all major appliances. You'll likely find that the dryer is listed as requiring 240-volt service - check manufacturer specifications for the specific circuit protection requirements.
If you're unsure about your campground's electrical service, inspect the pedestal box. A 30-amp connection will have a three-prong TT-30 outlet with a specific RV configuration, while 50-amp service has a four-prong outlet with a distinctly different configuration. Never attempt to use adapters or modifications to force a connection that isn't properly matched.
There's actually no repair needed for your dryer - it's functioning exactly as designed. The solution is finding appropriate electrical service for your needs. If you're currently at a campground with only 30-amp service, you have several options to consider for drying your clothes.
For immediate laundry needs, use the washer function normally (it operates fine on 30-amp power), then hang clothes to air dry using your coach's interior space, awning area, or portable drying racks. Many RVers install retractable clotheslines in their bathrooms or use expandable drying racks that store compactly when not in use.
Consider investing in a 12-volt portable clothes dryer or dehumidifier specifically designed for RV use. These units won't replace your built-in dryer's capacity but can help speed the drying process for smaller loads. Some RVers also use combination heating/cooling units with dedicated drying cycles that operate on 120-volt power.
For future trip planning, prioritize campgrounds advertising 50-amp electrical service. Many reservation systems allow you to filter by electrical service type. When calling campgrounds directly, specifically ask about 50-amp availability, as some parks have limited 50-amp sites that fill quickly during peak seasons.
You won't need professional repair services for this situation since your dryer is working correctly. However, if you're experiencing issues with your dryer even when connected to proper 50-amp service, that would warrant professional attention from a certified RV technician or Tiffin service center.
Consider consulting with an RV electrical specialist if you want to explore options for increasing your coach's flexibility with different power sources. Some owners install transfer switches or power management systems that can help optimize electrical usage, though these won't overcome the fundamental 240-volt requirement for dryer operation.
If you frequently camp at parks with limited 50-amp availability, an RV dealer might help you explore alternative laundry solutions or evaluate whether a different coach configuration better suits your camping style. However, this is more of a lifestyle consultation than a repair need.
