If it is gas, you need a certified technician. You mention glow plug, so it is the oil fired version there is help in the link. If it has a thermocouple, it may be failing as that is the device that registers that there is enough heat for the main burn.

The hose can be flushed out using a garden hose. The problem with wet vacs not sucking into the bucket is the float ball sticking. It rises and seals when the bucket has reached its fill level. This stops water reaching the motor.
All question need full 'make model (what it is)'.
That should supply the correct Search Query. I am guessing that model number is not formed correctly dashes of spaces are wrong. Or it is not a North American product so it isn't showing it to me.

If your furnace is shutting off and you are having to manually turn the thermostat back on, there could be a few different issues causing the problem. Here are a few things you can try to troubleshoot the issue:
Check the thermostat settings: Make sure the thermostat is set to the correct temperature and that the furnace is set to "heat" mode.
Check for a clogged air filter: A clogged air filter can restrict the airflow to the furnace, causing it to shut off. If you have recently replaced the air filter and the problem persists, try cleaning or replacing the filter again to see if that resolves the issue.
Check the furnace's limit switch: The limit switch is a safety device that shuts off the furnace if it becomes too hot. If the limit switch is malfunctioning, it can cause the furnace to shut off. You can try resetting the limit switch by turning the furnace off and then back on again.
Check for any visible issues: Inspect the furnace and its components for any visible issues that may be causing the furnace to shut off. This can include debris or foreign objects that may have gotten stuck in the furnace, or damage to the furnace or its components.
If you have tried these troubleshooting steps and the problem persists, it may be necessary to have the furnace serviced by a professional. A technician will be able to diagnose the problem and determine the necessary repairs.
There could be a few different issues causing the blower on your York furnace to run at low speed all the time. Here are a few things you can try to troubleshoot the issue:
Check the thermostat: Make sure the thermostat is set to the correct temperature and is functioning properly. If the thermostat is not working properly, it could cause the blower to run at low speed all the time.
Check the blower motor: Make sure the blower motor is not damaged and is running smoothly. You can try cleaning the motor and checking for any visible signs of damage.
Check the blower relay: The blower relay is a switch that controls the blower motor. Make sure the relay is functioning properly and not stuck in the "on" position. Check the control board: If the thermostat, blower motor, and blower relay are all in good condition, the problem may be with the control board. You can try resetting the control board by unplugging the furnace and waiting a few minutes before plugging it back in.
If these steps do not resolve the issue, you may need to take the furnace to a professional HVAC technician for further evaluation and repair. They will be able to diagnose the problem and recommend the necessary repairs.
Hi,
please check the vents in the rooms that are not cooling well. There might be a hole/leak in your heating system. The thermostat itself might not be the problem. If possible, please research google nest to check if it has multiple thermostats that can be used to more accurately state the average temperature across several rooms of your home.
You might need to get an hvac diagnostic to find and plug all of the leaks in your home before deciding to alter any of your heating system.
Thank you.
You likely you a coil cleaning. If you have access it’s something you can do just using caution as to not bending any fins. A small brush of some kind and a pump sprayer. Also take a water hose to the outdoor unit and clean that coil as well. Again being careful not to get water into where the electric is. Once that you can check your temp splits, return air temp vs supply air temp should be near 20 degrees. I.e. 75 return temp 55 supply temp.
