To fix the automatic vent opener on your Yardistry greenhouse model YM12842, follow these steps:
1. Inspect the Opener: Check if the current vent opener is damaged (e.g., bent, cracked). If so, replace it with a new unit. Choose a sturdier model if wind damage is a concern.
2. Remove the Cylinder: At the end of the warm season, remove the cylinder from the greenhouse and store it in a dry place.
3. Lubricate Before Reinstalling: Lubricate the cylinder each time before reinstalling it.
4. Install Correctly: - Follow the manufacturer’s instructions. - Ensure the opener is in the closed position before attaching. - Center the opener on the vent panel and align it with the roof rafter. - Insert the pin in hole B of the push rod. - Attach the window braces to the vent roof panel block and bottom vent block using two #10 x 1-1/4” pan screws per brace.
5. Add Wind Protection: Install chains on both sides of the vent to limit movement and prevent wind damage.
These steps will help ensure the vent opener functions correctly and lasts longer.

How do you adjust the automatic vent opener so that the vent opens at a lower temperature? Currently ours doesn’t open fully until it’s roughly 90 degrees inside the greenhouse.

To adjust the automatic vent opener for the Yardistry YM12842 to open at a lower temperature, place the black cylinder in the refrigerator for 5–7 minutes or until the cylinder rod fully retracts before installation. This helps calibrate the unit to start opening at a lower temperature.

Questions and answers
The automatic vent opener on my Yardistry greenhouse suddenly stopped working. How can I fix it?
To fix the automatic vent opener on your Yardistry greenhouse model YM12842, follow these steps:
1. Inspect the Opener: Check if the current vent opener is damaged (e.g., bent, cracked). If so, replace it with a new unit. Choose a sturdier model if wind damage is a concern.
2. Remove the Cylinder: At the end of the warm season, remove the cylinder from the greenhouse and store it in a dry place.
3. Lubricate Before Reinstalling: Lubricate the cylinder each time before reinstalling it.
4. Install Correctly:
- Follow the manufacturer’s instructions.
- Ensure the opener is in the closed position before attaching.
- Center the opener on the vent panel and align it with the roof rafter.
- Insert the pin in hole B of the push rod.
- Attach the window braces to the vent roof panel block and bottom vent block using two #10 x 1-1/4” pan screws per brace.
5. Add Wind Protection: Install chains on both sides of the vent to limit movement and prevent wind damage.
These steps will help ensure the vent opener functions correctly and lasts longer.

How do you adjust the automatic vent opener so that the vent opens at a lower temperature? Currently ours doesn’t open fully until it’s roughly 90 degrees inside the greenhouse.
To adjust the automatic vent opener for the Yardistry YM12842 to open at a lower temperature, place the black cylinder in the refrigerator for 5–7 minutes or until the cylinder rod fully retracts before installation. This helps calibrate the unit to start opening at a lower temperature.
