Raypak Analog Heater not reaching set Temp

[Farmer7185]

Hi all! Looking for help on where to look at this problem with my Raypak Analog gas heater - model 106A.

Heater will not warm the water above 84 degrees even with the thermostat turned all the way up. This has been going on for several weeks.

I used to be able to warm the water to 90 degrees with the thermostat turned up 3/4 of max.

I replaced the over temp switch in the spring to resolve a problem where the heater would not start.

I have not done any troubleshooting on this issue. Looking for advice on most logical cause and how to verify.

HeaTer does cycle on and off and maintains temp at 84 degrees.

Thanks so much in advance for any ideas!

Sounds like you need a new temperature sensor, possibly a new thermostat.
Temp. sensor - 011587F
T'stat - 011585F

Thermostat comes with a new sensor.
