I bought a house with a built-in Morgan Hot Tub in the sreen porch. The hot tub was probably installed when the house was built in 2002. Everything has worked fine for the past five years that I've lived here, until yesterday, when the blower bubbles quit. Everything seems to be working except for the blower. I was wondering how I should go about troubleshooting it.

Here is what I have determined.

The blower setting and push button do not make the blower work now, but the main jet control seems to cycle through the jets, heat and blowers. Jets and heat work, but blower does not.

could be lack of power getting to the blower or the blower itself is bad. Check for voltage across the two wires going to the blower to see if it's even getting power... if so, replace blower, if not, looks like a circuit board. FYI the circuit for the blower is repairable, but very few ppl would even attempt it. It's also the most common problem in blower failures.
