Tested the Voltage and it's all correct.

Yes we are using a spa cover. Also yes I ordered a heater that was 110V. Today still at 93F and the heater light has been on.

So we got a Nordic hot tub that we converted to 110V. It wasn't heating to 104F and the highest we could get it was 97F. So we replaced the heater and we replaced the control pad. Still nothing. So we looked at the circuit board today and noticed the Hi Temp sensor wasn't plugged in. Today was the first day we have seen the red heater light on located on the key pad. It has been 6 hours and the temp is still at 93F (same as this morning) I'm frustrated. Anyone have any ideas on why it won't heat up to the set temp of 104F??? We also have the filter cycle set to F6. Thanks in advance. Any thoughts welcome! Ryan
