Our Amana PTH153B50AJ Heat Pump code light is blinking indicating that the room thermistor needs to be replaced. I cannot find our users manual. How / where do I replace it? Are the parts available at most parts retailers?

Re: replace room thermistor error code
The thermistor is and electronic sensor and part of the thermostat, it is the solid state device that sends a very low voltage signal that the system converts into room temperature, thermistors are very accurate devices and much better than the old Bi-Metal type of sensor, you may just have a connection problem, or the thermistor may be defective, testing by a qualified tech is required on site to fund the final repair solution, but I suspect the cost to repair will be fairly modest.

This sounds like a freon problem your system probably has a leak in the system somewhere. Amana has tons of problems with there equipment. They make there coils paper thin and they split especially on a heatpump. Amana used to be a good brand and then got bought out by goodman manufacturing and have turned there product into ****. How old is this unit?
If the room air blower only puts out what feels like cold air and continues to run all the time it is an indication that the unit has a fault code stored in its CPU or central processing unit (better known as the circuit board). If the unit has a small viewing port either on the front panel or just behind the front panel, you can look into it and see a blinking LED light. Count the blinks and record. Sometimes there may be short and long blinks such 1 short and three long blinks. This could be an error code 13 or 31 depending upon the manufacturer. On the reverse side of the front panel, there should be a wiring diagram that also has a diagnostic chart that will tell you how to read the codes and where to start looking for issues based on the error code you recorded.
CODE= FP STATUS = Freeze Protection Engaged. The room temperature measured by the wirelessremote thermostat or indoor ambient thermistor active sensor falls below 40°F. SUGGESTED ACTION = No Action required. This setting will disengage when theroom temperature rises above 43°F Is sit helpful?
This is the link to find the manual for your unit. Make sure the model number is correct. You should be able to find the info you are looking for if it is possible to disable the energy saver. Hopefully this will help.
