It usually helps when you put the model numbers of the thermostat or furnace. Some need to be reset, some are simply a count down clock and its a reminder to change them.

The blower wheel probably is dirty. The unit is sensing that not enough air is flowing across the AC coil.

It may have fouled your plugs, but you can tke them out and clean them. Use a small blade and scrape the carbon off.
You could also take the egr valve off and try to clean it. Use a wire brush. also clean as best you can the passages under the valve, they can get plugged with carbon. Use a new gasket when you bolt the egr valve back down. Keep trying to get the fuel filter off, but the egr cleaning should help.

If you didn't turn the Master ON/OFF Switch to OFF, before removing the filter. That is the problem. To clear the error message. Turn the Master ON/OFF Switch to OFF, unplug the unit, remove the filter and reinstall it. Wait 10 minutes, plug the unit back in, turn the Master ON/OFF Switch to ON. The controls should have reset themselves and the clean filter light should not appear.

Hope this helped you solve the problem. Please let me know. Thanks.

There are many reasons a tankless heater will stop heating water. The first thing I would look for is a flashing red light on the burner indicator. The flash break down goes as follows

continuous blinking - typically means ignition failure or the unit is overheating; look for visible water inside the unit, have your gas pressure checked, or check the flame rod/igniter for buildup of debris

three blinks - typically indicates 16 error code; typically resolved by performing a descale

4 or 5 blinks - exotic error codes; for these you should definitely contact Noritz tech support

If there is no flashing light, first check your filter for debris. If the filter is clean, your flow sensor is probably stuck. Again I'd recommend contacting Noritz tech support to help you clean the flow sensor.

It this an escape Hybrid or no

you need a tune up new plugs wires and cap an rotor

There's something wrong with your aircon. Usually the lights will start to blink. Depending on the brand and model, the number of times it blinks will give you an error code which tells you what's spoilt. You may like to check this out http://www.astiquer.com/blinking.html

try cleaning The air filter in your set. It may be a thermal problem due to a clogged air filter.
