Because some types of spa heaters heat water slowly, it can be difficult to determine if the heater is working properly or at all. Before you call in a professional, take a few minutes to troubleshoot your spa heater and see if it is working correctly. Taking a few minutes of your own time can save you a great deal of money, particularly if you can either target the source of the problem or even repair it yourself.
Difficulty: Moderately Easy Instructions
Give your heater the appropriate amount of time to work. If you have a 120 volt spa heater, it is only going to heat cold water up at a rate of about two or three degrees per hour. A 240 volt heater will heat water at about six or seven degrees an hour, so don't expect miracles. If your spa has been out in the cold and you expect it to heat up in only a couple of hours -- that just isn't going to happen.
Make sure both the heater and the pump are on. Heaters can only heat the water if the pumps are working. After all, the pump sends water past the heater, and the heater heats up that water. If you have merely turned on the heater but not the pump, your water won't heat up. Worse, if you turn on the heater but haven't filled up the tub, your heater will burn itself out in seconds.
Check to see if this breaker has been broken. Your heater will be plugged into what is called a GFCI switch, essentially an outlet with an automatic breaker built in. Test it and push it in. If a breakage was the problem, then your heater will now begin to work. If the GFCI switch keeps breaking every time you reset it, the chances are that the element in your spa heater has burned out. If you are mechanically inclined, you may be able to replace a spa heater by yourself. But truthfully, with spas and electrics like this, it's better to let the pros handle this sort of job.
above is a Troubleshooting link, as is the link below, the link below is quite exhaustive in troubleshooting. below is a install manual for a Spa heater etc. use this to gain an understanding of how it all works and goes together, this will give you valuable insight, as to what can go wrong and how to isolate any problems. Please BE CAREFUL, you are dealing with the MAINS Voltages....
If you have ANY doubts, please call a professional, then you can get a "Quote" for any prospective repair, and you can then make an informed decision as to what to do. good Luck.

Just changed the thermisor and now the heater won't turn on. 4 green lights come on the control panel: pool on,spa on, aux 1 and aux 2. the underside has 3 green led lights lit and one red for cr21.

If all you did was replace the heat sensor check to be sure that you didn't losten any other wires on the header and on the board. Often when you pull the board for inspection you can pull other wires without knowing. Also be sure your baskets and filter are clean. Good luck.
