Common causes of reading stored codes and component test - keeprite (f/g)9mxt

• Need to find the last fault after it cleared

How to fix reading stored codes and component test - keeprite (f/g)9mxt: step by step

1. Remove any thermostat call and wait for delays to finish - codes cannot be read otherwise.
2. Leave 115 V on. Briefly (2-3 s) jumper TEST/TWIN to the thermostat C terminal (or briefly open one main limit wire).
3. A stored code flashes 4 times, then the component test starts. No stored code = test starts straight away.
4. During the test the inducer runs throughout; the igniter and each blower speed run 10-15 s in turn. Gas valve and HUM are not powered.
5. Stored codes survive power loss and are cleared after 72 hours.
6. Reading a code: count the short flashes for the first digit; the digit after + is the count of long flashes.
