Re: I have a nordyne elec furnace just put in a new heat...
You need to check the low voltage side to see if the t-stat is calling for heat. If it is, it is either the sequencer or a fuse to the heating elements (older model). But most likely the squencer. If you have a meter, you can check to see what side of the sequencer is burnt. Could also be a relay depending on the model number. If you get me the model number, I can send you a copy of the wiring diagram for the unit. This is the brand that I deal with.

But... but SL could also mean your spa is in SLEEP Mode!\
It is a Filtration/Heat mode.
You do not want your spa to be in that mode.
Unfortunately, way too many different spa manufacturers out there using 3 party vendors for their controls and so many different models! You will need to know your make, model & serial number of your controller to find out the sequence of buttons to push.
Difficult to answer without knowing the "Brand" of your Spa Support Pak System. Lets presume you have the most common basic pak available - Balboa. Press "Temp" button and then immediately press "Light". You will then sequence between 3 modes:
When your system is put into Spa mode the system draws water from the spa only to the heater to keep the spa at temp, this is why the overflow doesn't work and why you can not heat the pool in spa mode. If you could heat the pool this way it would take a very long time, since the spa is smaller then the pool. You can heat the pool and spa at the same time in pool mode. Water is pulled from the pool, heated and goes back into the pool and spa.
Might be the thermostat itself. If your mechanically inclined, then you can jump the wires at the thermostat to see if the thermostat is bad. It will only be 24v, but try to keep from touching the wires themselfs. Use a pair of needle nose pliers with insulated handles. Take off the front cover of the thermostat and you should see the wires. Depending on the wires they have hooked up, normally it is R- Power, W- Heat, Y- A/C, G- Fan. Without touching anything else, take your pliers and put both tips to R and W, hold it there steadily and wait for it to come on, its best to have someone at the furnace to hear it. If it comes on, then the thermostat is bad, if not, I would need more info on the problem. Hope this helps
If it were the sequencer, the heat wouldn't come on at all but the fan would blow. It's the fan relay but it could be the t-stat again. If you get a power surge when the unit is running, it can short out that portion only but typically, it will short out either the heat or the cool side depending on what is running not just the fan.
