Propane is a reliable and efficient energy source for many businesses, powering everything from forklifts to agricultural equipment.

But like any system, it can occasionally run into issues. A disruption in your propane supply can halt operations, costing you time and money.

As a business owner, knowing how to spot and troubleshoot common propane problems is essential. This guide will walk you through some frequent issues and what to do about them, so you can get your business back on track quickly.

Why Businesses Choose Propane

Before we dive into troubleshooting, it’s worth remembering why propane is a smart choice for commercial use. Businesses in Reading, PA, and across our service areas in Pennsylvania and New York rely on propane for its numerous advantages:

• Efficiency: Propane burns hotter and more efficiently than many other fuels, which can lead to significant cost savings on energy bills.
• Versatility: It can power a wide range of commercial applications, including heating systems, water heaters, forklifts, agricultural equipment, and backup generators.
• Reliability: With on-site storage, you have a dependable energy supply that isn’t affected by grid outages, ensuring your operations can continue without interruption.
• Environmental Friendliness: Propane is a clean-burning fuel listed in the 1990 Clean Air Act, producing fewer greenhouse gas emissions than electricity or gasoline.

Troubleshooting Common Propane System Issues

Even the most reliable systems can face problems. If your propane appliances aren’t working, here are a few steps you can take before calling for service.

1. Check Your Propane Tank Gauge
This might seem obvious, but it’s the most common reason for a service interruption. Many business owners get caught up in daily operations and forget to check their tank levels. If the gauge reads below 20%, you’re running low.

• What to do: If your tank is low or empty, contact your propane supplier immediately to schedule a delivery. At Sweetwater Propane, we offer bulk propane delivery services and can create a custom delivery schedule to ensure you never run out.

2. Look for Frost on the Tank
Have you noticed a layer of frost or ice on your propane tank, even on a warm day? This often indicates that you’re using propane faster than it can vaporize, which can happen if your tank is too small for your needs or during periods of high usage. This pressure drop can cause appliances to shut down.

• What to do: Reduce your propane usage to allow the tank pressure to stabilize. If this is a recurring problem, your tank may be undersized. Our commercial propane team can assess your needs and recommend the right-sized tank for your business.

3. Inspect Your Appliance Pilot Lights
If a specific appliance isn’t working, check its pilot light. A pilot light can go out due to a strong draft, a dirty orifice, or an interruption in gas flow.

• What to do: Follow the manufacturer’s instructions to safely relight the pilot. If it won’t stay lit, the thermocouple may be faulty or the orifice may need cleaning. This is a job best left to a professional.

4. Reset the Gas Line Regulator
Propane systems have a safety device that can shut off the gas flow if it detects a leak or a sudden change in pressure. This can sometimes be triggered accidentally.

• What to do: You can try resetting the system by turning off the gas valve on your tank, shutting off all your appliances, and then slowly turning the tank valve back on. Wait a few minutes before trying to relight your appliances. If the problem persists, you may have a leak. If you smell gas, immediately evacuate the area and call us or 911 from a safe distance.
