Overheating

Overheating and high temperature are the most common causes of blower malfunctioning. When overheating occurs, the blower motor thermal protection shuts down the unit. If your hot tub is running and you notice tiny bubbles or fewer bubbles in the water, it means the hot tub blower is facing the issue of overheating that could affect its function if left unattended for quite a time.

Water Damage in the Hot Tub

The water damage could affect the blower functions, and it could result in the malfunctioning of the spa blower. This happens when the unit is installed below the water level.

What are the Damages of a Malfunctioning Spa Blower?

The Function of Jets

Quality of Hydrotherapy

If the blower does not work efficiently and correctly, the quality of hydrotherapy and massage is compromised. The jets and the spa blower are responsible for giving you deep massage and hydrotherapy and if one does not work correctly and efficiently, the other could not show you the high-quality deep massage and comfort.

How to Repair and Replace the Spa Blower?

The malfunctioning spa blower should be repaired and replaced at the earliest. However, before going to start replacement, it would be better to check some other things that might cause a hindrance in the smooth functioning of the hot tub blower.

Therefore, before you opt to replace the spa blower, check the following things to ensure they are efficient and working correctly.

Check the Electricity Voltage

The spa blowers either run on 110V or on 220V and if they are not working correctly, make sure that they are getting the proper voltage. If you are providing them less electricity, it means they are not getting the sufficient energy to function correctly, and that’s why they are malfunctioning. However, if you give them electricity more than their requirements, it means you will fry them and ultimately affect their functions in the long run. Therefore, whenever you feel that the spa blowers are not working properly, China Royal Spa suggests to first check the electricity supply and voltage.

Check the GFCI Switch of the Hot Tub

If the voltage is accurate, China Royal Spa suggests checking the GFCI switch of the hot tub. If the water gets in the blower lines, the GFCI switch shuts down. Therefore, always make sure that a portion of air plumbing is above the water lines and the valves are working correctly.

Check the Wiring of the Hot Tub

Sometimes, the hot tub blower functions get affected because of the wiring issues of the hot tub. Therefore, if you observe a difference in the blower functions, China Royal Spa suggests checking the wiring of the hot tub.  If the wiring has some issues, it means the blower is efficient, and you have to fix the wiring only. However, if there are no issues with the wiring of the hot tub, it means you have to repair and replace the blower of the hot tub.

Check the Air Switch

Sometimes an issue in the air switch could affect the functions of your hot tub blower. Therefore, China Royal Spa suggests checking the air switch of your hot tub before starting the process of replacing the hot tub blower.

Once you have checked all the above-mentioned components of the hot tub and do not find any issue in these components, it means your hot tub blower has some problems, and you have to replace it at the earliest.
