Hi.

I recently purchased a used A.H. Equipment Corp. AM 32 Spa. It was set-up to run on 110 and was working fine. We moved the Spa to a new location and converted it to 220. All functions on the Spa seem to be working with the exception of heat.

Some observations:

Inside the access door there are three red lights labeled DS1, DS2, DS3 the top light (DS1) is lit the other two do not light.

After what I assume is , the heat cycle starts - it stops after a half hour or so and then "clicks" runs for a minute and stops every 20 min or so.

Any ideas on what may need to be replaced? Unfortunately the spa is two hours away from my home (and a spa parts store), so I would love to buy the most likely parts and bring them to the spa.. if it is possible to narrow down the problem.

I've uploaded the electrical schematic - and highlighted in red the two indicator lights that DO NOT GO ON. Hopefully someone can decipher - it's certainly beyond me!

Anyone have any ideas?

Thanks in advance!
