I have a York heat pump and the control is missing a

Customer Question

I have a York heat pump and the control is missing a resistor - which I believe allows the unit to reverse from cooling to heating. I'd like to replace the resistor rather than buying the control which is over $300.
JA: Did you double-check the thermostat's settings? And what about the filters?
Customer: This is a specific technical issue - not a trouble shooting situation.
JA: Do you plan on doing the work yourself?
Customer: I would have someone solder a new resistor back in place ...if I knew what is ohmic value was.
JA: Anything else we should know to help you best?
Customer: The resistor is at the very top of the control module with the markings REV H in a xcircle and I in a hexigon. the #'s 220325 are also present. The heat pump is a york model E2CSo36A06a

York Heat Pump M # E2CS036A06A Control Module issue. the resistor at the top of the module is missing. I believe it allows the change over from cooling to heating mode. The markings are a circle with "REV H" with a hexigon to the right with an "I" inside. the #'s 22032 are visible. On the back of the circuit board (same location) is the same REV H marking with a 2 in a hexigon. the # 220325 is visible. How do I find out what the "ohmic" value - or size/type - of the resistor is in order to have in soldered back in place. The unit runs fine otherwise.

I have a complete board in my hand and all I can say is that it is not a resistor, looks more like a led capacitor or thermistor, I will try to find out with york on monday, it does seem to be linked to the B at bottom of board.

Will get back to you

I have sent request for info to york and have yet received a answer, will get back to you for sure as soon as I do.

Gaztech....I gave you a tough assignment.....I continued to work on it myself and found a York Training Manual for the Stellar 2000 split system heat pump which included an Appendix F - Thermistor Chart - which gave the Heat Pump Sensors - Temperature Vs. Resistance info (Ohms) from -40 to 257 degrees fahrenheit. With that info I started searching for an outdoor ambient temperature thermistor with a resistance of +/- 25,396 at 41 degrees. I found something that seems to be working through "Kele" ( I purchased item ST-R24 which is described as a "Raw Sensor 10K 2 OHM THMS" for $11.00. The tech from Kele was helpful in that he could rate their ("kele's) Thermistors with what was required by York's control module by comparing different values I gave him from the temperature range/Ohm values on York's Appendix F. Hopefully this info will help you assist another customer in the future.
