What you can do yourself to troubleshoot your mobile boiler

If your circulator pump is cool and doesn’t appear to be operating, you may have a blown fuse

Due to the high temperature and pressure levels in mobile boiler systems, several malfunctions require a professional’s experience and knowledge. However, some boiler problems can be resolved by the homeowner. When your mobile boiler provides very little heat or no heat at all, there are several possible causes. You should begin troubleshooting with the proper causes of repairs, such as the pilot light and temperature control unit. The first component to check is your control unit setting. Ensure your control unit is set on heat mode and is set above your room temperature. Check the circuit panel or fuse box for a tripped breaker or blown fuse. If your mobile boiler is using a sitting pilot light, check to ensure it is on. If not, try to light it manually! A thermocouple malfunction is a proper cause for a pilot light that won’t come on. This is the component that shuts off gas automatically. It could also be caused by air from a defective seal that is extinguishing the pilot. Check your hot-surface ignitor. Hot-surface ignitors are designed to last up to several years. This component should be replaced every 3 years during preventive services for your HVAC system to avoid malfunctions. Also, check your circulator pump to confirm whether it is working properly. If your circulator pump is cool and doesn’t appear to be operating, you may have a blown fuse. If your pump is hot, the malfunction could be with the motor, run capacitor, or pump. If you are experiencing water leaks from your mobile boiler, check for a faulty pump or faulty relief valve.
