I have a 1998 Trane heat pump. American Standard Inc. The Trane Company Tyler tx model no: TWV036B140A0 with a serial number of D11332785. One half HP motor and 3.3fl amps. volts 200-230.
My question is that when the air is turned on a repetative clicking can be heard comming from the inside exchange box which houses the evaporator core, the blower motor, a transformer for thermostatic control and some buss/relay looking things....this clicking will stop after turning on the air...but periodically returns and it seems to be increasing in occurence.... what can i do.... relay?
thank you in advance..... David
