1995 Landmark Temp issue
« on: June 21, 2020, 12:39:57 pm »
Recently obtained 1995 Hot Spring Landmark (SN: S 15-1046) for pennies.  Always stored inside, hardly used. Great shape. Had techs look over before we moved it to our house.  They said everything but light works; however until itís run for a while canít guarantee.  No worries.  Itís all hooked up and working - Jets and pumps seem fine. No leaks anywhere.  Found original manual online with supplemental for my model.  Followed startup instructions. Waited about 8 hrs and tested water.  Hot!!!! Then an hour later Hi Temp tripped.  Reset and turned dial from 5 to 1.  Didnít cool. Tripped again. I tested thermistors Ohms and found Control one was bad.  Replaced. (I bought both Thermistors to be safe). Kept dial at 1 to bring up gradually.  Hi temp tripped again. Turned temp off.  Replaced Hi-Temp Thermistor just in case. Turned temp dial down below 1. Waited an hour and temp at 104-105. (Measured with body thermostat). I know it takes a few hours for temp to decline.  However with the dial so low, it shouldnít be getting beyond 100 degrees.  If I check in a few hours and itís still at 104, Iím thinking calibrate thermostat, heating element calcified or control knob is bad.  (Iíll check Ohm reading again too against temp).  Thoughts? 

Update 1 (1:45 Eastern):  Ran Jets for 17 minutes, temp dropped 1 degree; dial still below 1. Iíll continue to test throughout the day and see if temp continues to drop. Then slowly increase dial after a few days.)
Update 2 (3:25 pm Eastern:  Temp now down to 103 but the Hi-Temp switch kicked in.  Reset.
Update 3 (6:45 PM Eastern): Temp checked each hour since last update. Temp 102 and holding since 5:30. I donít see water circulating even a little.  Bad circulation pump possibly. Has not tripped again.
Update 4 9:45 AM:  Went out to last night eat came back and at at 9:30.  Temp 102. Solid light no trip.  Dial still below 1. Enjoyed some time in. Checked this morning and light still solid. Tub didnít not trip.  I didnít test temp with thermometer but it felt same. Good news is no reset.

hupomeno,

I just joined here and this is my first post.  I purchased a Tiger River Bengal Spa back in 1996 new.  Anyway, the 30amp breaker in my sub panel was tripping when my heater would kick on.  My 2 breakers were 20+ years old.  I replaced both of them one for the heater and the other for the lighting and trickle pump.  Got them at home depot shipped in 2 days!

Good luck!
