My spa has a blown fuse

My spa has a blown fuse

Is this ok or do I need to worry about it? Yes maybe no, generally a fuse protects a circuit on a appliance a electrical component. So If a fuse has blown it means something has happened and the amperage or power drawn exceeded the limit of the fuse. The circuit being protected may be a pool or spa pump, a spa blower, lights, radio, other accessory, or a control board. Each of these things can have very different circumstances. If nothing works and the spa has electric going to it the most likely cause would be a main fuse. This could be a fuse protecting the actual legs coming in if so it would most likely be a 20 or 30 amp fuse in a holder attached to the box in which the controls or circuit board are contained. Or it could be a fuse on the circuit board itself that is allowing the system to boot up and delivers voltage down the load of appliance. These fuses may blow due to, loose incoming connections at the spa at the breaker or a bad connection in the holder. If this is not the case then there may have been a voltage spike by the electric company or a lightening hit in close proximity to the spa. There are tools a tech will use to test the circuits ability to deliver sufficient power. Those tools include a meter for amperage testing and voltage testing. They will be looking at the power coming in to see if there is a drop in voltage across the line connections throughout the wiring to the unit. Spas and hot tubs draw a certain amount of amperage when they are running correctly. If a motor is going bad the voltage may exceed its predefined limits. This may be the reason for a blown fuse on the incoming legs of power. Shorts to ground are a real danger which should cause the GFCI breaker to trip most likely before a fuse would blow. Note all spas and in many states pools must be GFCI protected. If there is not a GFCI circuit breaker a short to ground a, spa heater, spa motor, blower motor, spa circuit board, or other spa nad hot tub component it can have a deadly result. Never use a spa / hot tub that does not have a GFCI. Under no circumstance if you attempt to replace a fuse and it blows again in a small amount of time, lets say within several weeks should you replace it again. It is giving you a real time warning that something is wrong. Ignoring this warning will not maybe do damage to something in the unit. It can be guaranteed that damage will be costly and possibly dangerous. If you are attempting to repair a unit it yourself you are taking a considerable amount of liability. I would like suggest you give electricity a huge amount of respect and common sense. The best and safest route is to find a qualified technician to look the problem.
